- In this professional genealogist reacts I watch "Twins get 'mystifying' DNA ancestry test results (Marketplace)" from CBC. I had soooo much to say about this video that there is a lot of me ranting, even after cutting out an extra 10 minutes of ranting.
Check out the original video - • Twins get 'mystifying'...

The stupidest thing about this video (great rants, btw) is that they don't even talk about the history of Italy. Italy has historically been a huge melting pot of peoples for at least 3000 years! What even is "Italian"? Of course if you're from Italy you're likely to get results from all over the Mediterranean and even North Africa. I heard of one guy whose family was from Sicily and he was very upset that his results didn't show up as "Italian". What did they show? North Africa, Greece and the Balkans, the Middle East. It's not a surprise! Look at the history, for goodness sake. Just terrible journalism in that video.
Thank you!
Absolutely.
Amen!!! Its because the nation states that "feed" us(feed off of us) we are so trained by them to think in terms of "nationality" instead of humanity ...this is a perfect examples to open up the trained mind and undo that training👍
Yes! I had to explain to my dad that our mixture of South Italian, North Italian, Greek, and French WAS Sicilian, especially in the Palermo area. He didn’t understand 🤦🏻♀️
Yeah, Mycenean culture of Ancient times, which itself probably derived from Crete (the Mediterranean island) arrived to southern Italy ~2 millennia B.C.E., some Minoan Crete subgroup went to Egypt and got expelled, some of the group ended up in Philistine, modern day Gaza. Then they got conquered by the Romans, which themselves got some gene input from the Italian peninsula(at least the high classes). Who knows where these genes come. From my understanding, autosomal DNA don't trace so far as ancient times.
I would think people would be happy knowing the information and websites evolve over time when the companies gain more knowledge. Also, super sassy video lol
Haha, it certainly is the sassiest I have been in any video!
@@GeneaVlogger AncestryDNA has done multiple updates over the past few years. People say jokingly that they don't even recognize themselves from previous updates. Sometimes the results end up going close to full circle. It's a huge business moneymaker and the ads are pie in the sky. Another issue that was not brought to light is that many people don't even take time to research a family tree. However, like you mentioned, the best part of these companies testing is in the matches. That's why I appreciate MyHeritage since they provide a large International base of DNA matches.
@@bobbykevinabramsonhennesey1625 I need to get on that My Heritage site. I've only done Ancestry.
Well, that is a general view I've encountered from people who want to think they know more than a professional. The fact that scientists in their fields are constantly challenging the current best hypotheses and continually updating information, to them, means 'science' can't be trusted.
Like, with the most recent Ancestry update, I went from abt 25% Irish to 25% Scottish. But, with that area being so fuzzy, and my records showing 2nd and 3rd great grandparents in Ireland, that doesn't change the fact that they were Irish. Maybe those readings are slightly off, or maybe if I dig deeper, I'll see that those families came from an area considered Scottish by the current groupings.
I am an adoptee that has found a half-brother and his son and a few days ago a half-sister. I talked to my half-sister for a long time. She knows the name of her birth mother and when she tests with 23 and me we will find out if we share a birth mother. For someone that has no idea who or where they came from this is huge. By the way, the reason I believe we share the same birth mother (99% sure) is that we both have the Italian, Greek, Balkan results and she knows that her birth mother was Italian American. Thru another DNA relative, I might know who she is (80%sure). We also know that there are more of us siblings out there and we are hoping to find them. Finding family is the most important part of discovering that I was adopted. I have a great adopted family and know I'm finding a second family. The ethnicity estimates are fun and it gives you an idea of where your ancestors came from but like I said finding and connecting with my siblings half or full if they are out there is the most important and best part. Sorry for making this so long.
As a Canadian who watches CBC (Canadian Broadcasting Corporation) I remember being totally ticked off by the whole thing. I had my DNA done by the largest company about a year before this program aired. My results where bang on point with my genealogy records done by other family members. I have direct ancestor records going back to the 1500s on my mother's mother's side and to the mid-fifteen hundreds on my father's mother's side. I have distant native American distant cousins I've known life-long, from my 4th. great-grandmother 1781-1858. My DNA results surprised me by showing 1% native DNA. I didn't thing there would be any after so many generations. The most surprising thing of all was finding a half-brother two years after I took the test. Because of Covid-19 we've not been able to meet yet.
@Yarrow Bumblefoot as a québécois in the U.S., could you please tell me which dna tests you took? My father’s family have passed on and were pretty tight lipped about their family tree.
As a geneticist and someone interested in family history I love your videos and find them very entertaining and informative! It's great you explain the nuances of these tests, as so many people don't completely understand them.
As a geneticist can you give us your opinion about the guy who said the twins should have exact DNA? As far as I know that’s not true, that’s why has cases where a twin has a genetic disease, or is more prone to it, while the other doesn’t. Also how much back we go in the genealogy line more mixed our DNA will be when it comes to race. I Brazilian and just by looking to my great grandparents I have origin from 3 diferente continents and 6 different countries.
I not only found true blood cousins through my DNA but also important health information and confirmation of a lot of my family tree hard work.
Why didn't they look at the possible genetic matches? Because it doesn't fit their agenda.
I agree with your assessment of this. I think the problem is that you have people that don't have an understanding of DNA and DNA testing companies reporting to consumers that may not have an understanding of both either which could deter people from helping the data bases grow. They were so focused on the ethnicity percentages and also probably unaware of the history of human migrations. Yes, the ethnicity part is the fun part of DNA testing. I've taken Ancestry, MyHeritage, 23andMe and FTDNA(Big Y, mtDNA, FF) and most of the them are very similar in their resulting locations, just not their percentages.
I agree it's almost like they set out with a purpose to debunk them. I have used 23 & me and it does tell you up front that it estimates an how it's done, if they buy _without_ reading then that isn't the company's fault.
I agree. My sister and I l did different tests, and our results were very similar. I expected a few percentage points off due to different population databases for each company.
I agree with your frustration. Etnicity is a social construct, and DNA is a biological fact. Trying to compare that is not easy
They presented the update aspect as negative, while I consider it one hell of a good feature. Before watching the videos of this channel, I didn't know they update the results as the database increase. To me, it was like a snapshot result based on current database.
Thanks for the explanations and I totally agree with you about how bad they presented, emphasizing detrimental opinions to the science supporting it.
Identical twins are not identical. It’s more precisely to call them monozygotic. After the zygote has divided into two individuals, some genes turn on and/or off differently between the twins. My “identical twins” share 99.8 % (or was it 99.9, I don’t remember exactly but it’s a very small amount) DNA according to MyHeritage, and that is not necessarily a misreading but could be due to the phenomenon of different genes turning on and off. One of my girls is 100% Scandinavian the other one is 99.2% Scandinavian and 0.8% Inuit. I share more DNA with one of them, also some distant matches with one and not the other. I just think it’s fascinating. I am more baffled by my British ethnicity which is 5.4% at My Heritage and 21% according to FamilyTree DNA. I don’t know of any British ancestors and my tree goes back to 1830 on the branch I know the least about, so there I have something to dig into..
"Enægget"/"Eineggjaður" as we would say.
Yes! Most people don’t realize there are several types of identical twins. My friend has a set of mirror twins within her triplet boys. One is left handed, one is right handed. One has hair that naturally parts on the left, the other on the right. And they both have hetereochromia iridium but opposite of each other.
I agree with the magic difference those as well. I was raised by my Swedish English French mother. She literally only has three European lines of ancestry. Yet, I get some low percent of Finnish on Ancestry vs 23% Swedish on MyHeritage. Granted, my mother's 3 lineages are #1 Proven Mayflower, #2 Colonial English, #3 Colonial French Canada. So, my mom's ancestry has been preserve d by family and extended genealogists since the Earl colonies. I was given those tree names decades ago. #4 my Swedish ancestors also preserved their family tree so I had that too because my first Swedish Great Great Grandfather married my Colonial English Great Great Grandmother near the American Revolution and they lived on a Territory before it became a state. I have all kinds of history from my mother's side. So, I know I have signicant Swedish but Myheritage shows that. However, researching one Swedish ancestry line that I always wondered was different in surname Conventions was Hans Dufva. I found that that surname was Finnish and a Dufva nobleman was accepted into Sweden as part of their nobility. All that would be at a time when wats between Nordic Kingdoms were constantly in radical boundary shifts as one King may dominate the lands and nobility of another kingdom. So then it made sense to me. This Finnish Boundary plus trade and wars and blurring of heritage in Sweden. Old Sweden of 1700 when my Swede ancestors arrived are diverged from the Modern Swedes of Sweden. But never the less a distant cousin in Sweden who my Swedish American relatives keep in touch with on Facebook too, she and her daughter are still recognizable relatives. I noticed on my Swedish side, traits of our family clone dominated. Lots of cousins look alike. One brother is the spitting image of our Great Grandfather, literally. I thought I did not look like them. Then I had looked at an old photo of my Great Grandfather. At the same age as he was then, I now look like him as a female. He was very fine featured not the depiction of a burly Viking. I think that DNA traits switch on and off over time. As a baby I looked like my father. Over time, I looked like my father or my mother. Another anomoly is that my father was half Scottish and at Ancestry and Myheritage I am about 22-23% Scottish. English in both is roughly the same. My friend to UK is Scottish and Irish. She had a tremendous amount of Nordic vs anything she ever imagined. It might not be all Viking. My Swedish ancestors travelled to England as per travel records. They were traveling much more than people likely imagine. My 3rd Great Grandfather has either a brother or cousin married to an English woman. It is a bit odd that a Swedish man traveled to a Swedish colonizd Territory with a new bride of an established Colonial bride. It must be that travel to Great Britain was an important part of establishing both family and trade.
My identical twin and I share 100% of our DNA and I share 99.90% of my DNA with her daughter (according to 23andme).
When I first watched the original video, my reaction was the same as Jarrett's. As the daughter of an adoptee, I was able to find my father's birth parents. More surprisingly, I found branches of my mother's family that had not been in contact (yet lived in the same city) for over 100 years!
I did mine through both Ancestry and 23 and me. I had a lot of my mom side of the family also tested so I had no surprise there. My father side is where I got the most help and verified my native American heritage. I had a couple of half uncle and half 1st cousin's. But a ton of 2nd, 3rd, 4th cousin's that all help fill in my native American all the way to my 2nd great grandmother. You do need have cousin's test.
Matching cousins narrows down whatever line you trace. Me and family have proven "family stories" false through DNA matching with cousins ❤️ genetic matches are gold in making family trees
I really wish everyone looked at these tests as more of a long term investment lol, with updates and more research and in conjunction with a paper trail, it’s super helpful and will only improve over time
Update; lolll the guy saying there isn’t science is totally disregarding so many factors
Long term investment is a really good way to put it! Although I know a lot of people just interested in the admixture, and nothing else, would unfortunately probably be turned off by that.
What a shame none of these journalists talk about genetic matches !
This report didn't get totally what these DNA tests are about and what they can give you...
I have seen and commented on this video you are reviewing and before you even start I have to say that this "news" story makes me so mad. The bias and the way they keep back important information just makes me so angry.
I a 100% agree with you, when I watched that video in 2019 made me sooooo angry, not only because of how they were saying things, but.. lets face it, even if a person were to take two tests in the same company will come 100% the same, you will come up as your identical twin...
AAAANNND... not because a person was born in a certain country (and their family have been living there for centuries), means that their DNA is from there, and DNA knows no "country boundaries" countries names have changed, countries have been conquered and passed to different other countries hands... etc
I remember watching this segment. LOL, amusing.
And you're correct, we have no idea how it was edited from the group discussion. I know someone who was once an expert for a show and they completely altered what he said in post. But, glasses guy, he said what he said.
Through Ancestry DNA match I found an Aunt we never knew existed. I flew out to meet her and her kids, and it was so delightful. They really should do commercials about DNA matches.
That is so awesome and incredible!
"On average, pairs of twins have genomes that differ by an average of 5.2 mutations that occur early in development"
Google is your best friend. They are twins and don't even know their own existence.
It’s really unfortunate that advertising for these services have pushed the admixture so much when they change their calculations and groupings fairly regularly, so even one’s own results aren’t guaranteed to remain the same on a single test over time.
The admix is kind of nice in combination with my own research to more or less verify I’ve positively documented family from the right regions, but the genetic matches and their own trees are truthfully far more useful for building out branches I didn’t know about.
But your average person doesn’t actually want to spend time slogging through old documents and pestering family for stories and information to build a comprehensive tree, I suppose.
The genetic matches helped me find the missing branch of my great grandmother's sister (they had emigrated to the US between censuses, but to me they just vanished).
@@hawkeyescoffee6399 that’s awesome! I found a branch of my family that I didn’t know had immigrated to the US using the genetic matches. They were the only branch of the family not to have their surname Anglicized upon entry, so I never spotted them when searching records.
Loved your rant, I was as frustrated as you. I suspect (or at least hope) that there was a lot of clever editing when it came to the computational biologists because I would expect better from them. I only have 2 years of undergrad classes in molecular biology and I know how all this works.
I'm also pretty sure that most, if not all, websites tell you how the results are calculated using estimates etc _before_ you buy the kit. It seems to me like they went into this with a clear agenda and with the intention of "debunking" them regardless of what was found. The results weren't that different, they were within expected parameters. And like you pointed out, their raw dna wasn't identical close is not the same as 100%, only takes few loci to be different to produce the changes seen in these results.
This video annoyed me to no end when it came out. This reaction has been a salve.
my great aunt (who was adopted as a baby) took one of the tests when she was in her 90s and found 4 half sisters still living. One of my 4th cousins who was adopted was able to find her bio mom by piecing together various 4th cousins.
I am from an endogenous population and it makes DNA research tricky. What is nice is that genealogy has been a thing here for a long time so a lot of people can trace back to the 15th century. And also not marry to close. A man in the 17th century did a full genealogy of his mothers side. "In his genealogy, Bureus included all the family ancestors and descendants, whether male or female and regardless of what social standing or legitimacy each family member might have represented, thus making it possible for many modern-day families to trace their ancestry back to the Bure kinship" from Wikipedia
The problem with marketing finding family members instead of ethnicity is that most people THiNK they know their family members. Often there are interesting family stories about ethnicity (in more mixed countries) that may lure consumers to buy DNA tests.
Also, you can’t rely on family matches WANTING to make contact. Pushing that may set people up for disappointment. It’s funny, my newly found American cousins are happy to make contact. My Scottish cousins, who I would really like to talk to, ignore my messages.
Love your delivery & the way you talk thru things that you know ... or might be obvious to those schooled in genetics or to the average genealogist... thank you for sharing your knowledge 👌
Also you're not afraid to say you don't know something, but with the info you do give us, we can look into it ourselves.
I’m an identical twin. Our CM’s to matches are pretty much the same within 5cms.
This was my favorite video, made my Monday a whole lot better! Thank you 😉
Since I've discovered you, I'm liking your genealogy videos. You seem well informed. This video actually made me subscribe. I like the way you think about science. After running into a dead end on one ancestor, I was pretty certain I knew who she was but never could prove it. When I did Ancestry DNA I verified it. At first there were no matches but over the last couple of years, more and more distant matches showed up for that ancestor, enough so that it pretty much sealed the deal with who that was. There was no marriage record, divorce record, and that female died with her maiden name. Illegitimate child, divorce, or annulment are my assumptions. It was in the late 1700's. She was from a wealthy family and he was from a poor family, so I can see how that could have happened. Also, they lived very near each other and the male child they had was raised by a different family, and which left him in their will.
In addition, I had no idea I had Dutch ancestry until I did my tree and found immigrants from the Netherlands. My DNA confirmed it. If you do a family tree, DNA testing is almost necessary to verify some lines. I also did CRIgenetics for health testing and discovered a "disease" I didn't know existed and it helped me in diagnosing it. Their genetic results are really different from Ancestry, but they make sense. They say there is some Italian, German, etc., when I thought I should be more English, but we know that many Germanic and Italian peoples settled in England. Ancestry showed much less German and no Italian.
Thanks for doing this video. I watched it on Marketplace when it first aired and so much about it irked me. Love your reactions and rants!
I’m so glad you finally reacted to this video!!! You were so fired up. That’s how I felt when I watched it too. Lol
Keep making videos bro we love it
I'm not even a professional and this video was pissing me off so much lol. I understand why you were ranting, they were definitely trying to push some narrative 🙄
How does your comment say it was posted a month ago. Also I watch the video he’s reacting to n I agree with you cause it definitely made me not want to do it.

do the people that you react too know about your videos? I hope they watch your explanations.
PS: I completely agree with your reaction....fear mongers!!!!!
Some do, some don't. If the original creator comments on my reaction I will pin their comment. A few who have done so - UsefulCharts, Bahador Alast, and Life of Janice and Malik. A few others have as well but I can't remember all who have commented. I have been hoping someone goes meta and makes a reaction to my reaction of them!
One of the best reactions so far, loved it! :)
This is about as good as you can get with a show like Marketplace. As a Canadian I am more than familiar with both the CBC and their consumer advocate program Marketplace. The problem with shows like marketplace is they make their living from finding problems and hi-lighting and exaggerating them. They are only too eager to ignore the positive for the negative.
Great video! I love the frustration about the perceptions of science, it shows its your thing.
I LOVE your rants!!!! I would LOVE the Science video!!! That would be amazing! I also subscribed. Your rants help me learn so much.
Unfortunately, the people we'd like to test, have already passed on by a few years. I'm hoping to use MyHeritage DNA for sure, but might do ancestryDNA and definitely need to do LivingDNA because I do have English, Irish and Scottish heritage as well. I might even do the test twice, a few years apart, to see what changes are had.
I find that you are quite sensible and knowledgeable about ancestry and DNA and that is nice to see. So far watching your videos I have not heard you say anything that is strange or not true. You are one of the few persons who I find know much more than myself about these DNA tests. Love your videos. Thanks.
i studied biology, production horticulture and plant breeding when it comes to genetics we are still in the early stages of creating genetic catalogues like this, also accuracy level with anything like this will be all over the place in the early years until the sample sizes increase and the margins of error decreases over time especially when you have multiple teams using their methodologies eventually this will iron itself out as the years go on. we are doing the same thing with reclassification of plants as we are into the genetics of them and turning plant classification on it head, but that is the great thing about it we are learning new things all the time. really the term recreational science grates on me, there is no such thing, i really don't understand what people think science is, they believe it to be this all telling truth that is never wrong. there is no such thing as a scientific consensus and all things stand on the margins of error.
professor Jacob Bronowski said it best "Science is a very human form of knowledge. We are always at the brink of the known; we always feel forward for what is to be hoped. Every judgment in science stands on the edge of error and is personal. Science is a tribute to what we can know although we are fallible."
History is important. Sicily was originally a Greek colony which is potentially why they got such a high % of Balkan.
I've tested a number of genetic companies. I still follow the paper trail. My Mom's Dad came from Torino, Italy. Her Mom was born in Illinois. Dad's Mom and Dad came from Poland. 23andme eventually said I was Italian. Many of Mom's side took the 23andme test, as well. My Polish side did too. A first cousin and his kids also took the 23andme test and I cross reference our DNA cousins for matches.
Have you seen the new ancient ancestry breakdown of Hunter Gatherers, Farmers and Metal Age Invaders and Non European on FTDNA?
Yes. Not very useful genealogically but definitely fun to check out.
@@GeneaVlogger it is scientifically significant it explains the climates effect on Migration the population changes caused by Technology that Bronze Age brought. The genes that make people able to eat grains and lactose intolerance affected who won the massive wars of the Warring States Period and Mongol invasion. The Chinese we’re lactose intolerant the Mongols were not, making it possible for large armies to move swiftly without stores of grain provisions. Mongols took herds of horses and drank their milk and made cheeses.
@@GeneaVlogger it was potatoes that exploded the UK population and famine that drove the Irish diaspora. It was New England White Pine that built ships and masts that powered the British Navy.
Genealogy can really bring out the interest in history, can't it? I found out my maternal haplogroup is the same as the Sami people and Cro Magnons, and I have the same gene as those people from Italy and China who live very long lives.
@@GeneaVlogger ok so I uploaded my dna to Gedmatch and I did the Archaic Matches and Started matching at 2.0 cM to 3 of the ancient people. Rathlin1, Ireland, Bichon Switzerland and Kotias Georgia. When I go to 1.0 cM dozens light up. 13.7 k BP on the Bichon guy. When I go to .5 the whole screen is orange. Now I have proof i am a caveman. The only two I don’t share DNA with is Mezmaiskaya, Russia Neanderthal and the Famous Otzi Iceman.
Dude, I LOVE your videos !!!
My maternal grandmother began working on our family tree like back in the 90s. She even went to Utah at the Mormon genealogy center and put together a huge family tree notebook. She sent me a copy. It's truly amazing. I wish she were alive today for these DNA sites. My father was Puerto Rican. So, basically I already knew what my DNA would consist of. Sure enough, Ancestry is quite accurate based on what I already know about my family. I even found relatives who personally knew others we are related to who died decades ago. Like my great Aunt Willa on my maternal grandfather's side. I found a relative who shares some DNA with me who knew her! She died around 1975!
Your rants are more than justified!!!
Ah, if some of these videos would go after *MATCHES*, not ethnicities.
There are so many reasons for these things to be variable.
The maps at min 33:18 are still basically the same... highlighting the same countries/areas, with similar overlaps...
Exactly this. Like can’t you tell that the maps cover the same areas, even if the names are different? Many of those labels would have been meaningless 100-200 years ago.
I had the same reaction as you to this video. It made me so frustrated.
They shouldn't use identical twins. They should test the same person twice to see if the reading comes out differently.
One of the twins has had a son, so she could be a microchimera (meaning some of her son's DNA has infused into her own). This could account for the results coming out differently.
If the same person tested twice it would likely be very similar to identical twins because there would be different errors in each reading, creating a similar ~1% error.
@@GeneaVlogger That actually happened. The Family Historian Channel did that with AncestryDNA and though there were some differences in ethnicity results, they could tell that it came from him even though he changed his name and all of that.
I am Afro-Caribbean and was curious of my genetics. I was surprised by some of my results: 85% a mix of West African countries and 15% western European. I was able to connect with relatives I didn’t even know I had. All thanks to Ancestry DNA.
I like the way you think, plus you've taught me much about genealogy. Thank you!
I founs my birth father thanks to Ancestry. I never knew that side of my family. My uncle (my father's half brother) took the test and we were able to connect the dots. The moment he met me he told me that I looked so much llike one of his older brothers, he bought his brother a test and found out he was in fact my father!
Great video. And as a fan, I do enjoy the rants! lol But you're right. They don't get into genetic matches or talk about the upside of the science at all. And what part of "estimates" in "ethnicity estimates" did they no understand? All of it, apparently.
I found this a really useful video. I used the several DNA test I took as a starting point to research my family tree. I found that my journey up the tree confirmed the DNA results and helped make far more sense of everything- each supported the other- DNA vs Genealogy. I believe that most folks take a test expecting a definite answer regarding their ancestry and too few take that next step to research their tree. Researching the tree has been one of the most fascinating informative and amazing experiences of my life. I have a far greater sense of who I am where I came from and my family's place in the world. The cousin matches have confirmed time and again that my genealogical research is accurate, I've made contact with so many distant relatives and discovered so many interesting stories about how my family has emigrated to the four corners of the earth- uncovering so much information about very ordinary but incredible people. I see the physical traits we share in the many photos shared and of course the similar career paths many have taken who have never met and and on the other side of the world or generations apart- that really made a big impression and made me really think about just how much we inherit in our DNA apart form eye colour and hair colour- there is obviously a lot more that can be studied in this field.
the funny thing is that the media person did not mention that there is still a higher trust rate with all 5 of those companies than there is of media persons. keep the rants up :)
I love your measured explanations. The CBC show seems to be aimed at simplifying genetic genealogy, and creating "controversy". It IS science, and it is not wrong, but it can be a little misleading, if you are only looking at the exact ancestry. I am so lucky that I got to speak directly with Family Tree DNA's founder Bennet Greenspan, when I did my first DNA tests, 20 years ago. He was really warm and funny/witty. He said, oh yeah, you look like an Irish or Scottish guy certainly, etc. He explained so much to me, that these shows, CBC and Who Do You Think You Are, not hooked me, because I got the gist of the science (on a simplified level). Greek people get Balkan, Italian people get Balkan or Middle Eastern, etc., but it is not wrong, just misleading, if you don't understand peoples' migratory histories.
I have an endogamous family tree all my greatgrandfathers ancestors were related with being first cousins or second cousins etc., these families can be traces back to 1300. Than some go even further in to nobility which again are all related. So. I decent from certain people 10 times or more they all married with in maybe 5 to 10 families. They were wealthy farmers.
Did these ladies try tot trace the paperwork of their ancestors.
Only just got to the part where they mail the tests off. They don't look like "identical" to me, I see several features that are different but that's obviously not relevant, what matters is that they both developed from the same zygote that split in two. However, the process of cell development development after that division can still develop independent mutations in the womb which can muddy some readings. And we still have so much to learn yet so it is still entirely possible that some genes can get dropped or amplified during or post split. I'm guessing from the title of their vid and the differences in their features that they are going to be the kind who have had one develop identifiable mutations.
I'd be interested to know how they determined that they are identical twins. Eg did they actually get DNA tested in childhood, did they assume based on the amniotic sacs, or did they assume just from phenotypic similarly?
You're right that Living DNA gives you interesting breakdowns in the British Isles. They pin down what county or region of the UK your ancestors come from. My DNA admixtures were pretty boring; my first run from Ancestry was 92% British (they are down to 62% British in the most recent sort). I was excited to get a breakdown as to where in Britain my family lived. Living DNA also give mitochondrial DNA results which adds to the interest of their results.
Totally agree with you. I think part of the problem is The Big Bang Theory and similar shows. "The science is settled." SCIENCE is a process, people! Science is never settled. Also ACCURATE and ESTIMATE are not antonyms. Can we send the reporter and policy guy to a statistics class and a basic lab class? Like a 6th grade lab class, where they teach you about variables and make you fill out Punnett squares. Also, while the admixtures are fun (and in my case impressively specific), I bought it for the genetic matches.
Some of the major issues that limit the ethnic approximations by these companies: (a) this type of science is dependent on statistical estimates that are based on a reference database which is only as good as that particular reference data (in the case of these private companies, they do not share their reference data) - for instance, various tests may be more accurate for certain groups of people that are better represented within their reference data (population bias). This is why I appreciate that you have noted in some of your other videos the issue that certain companies have better databases for various regions or continents; (b) as you mentioned, there's a certain margin of error involved in data analysis. Even under the strictest standards, there is always a margin of error that is inherent in statistical analysis which can result in incorrect findings. Error of results can occurr for many reasons, such as: random chance, issues with the sampling or reference data used for comparison, or any other factors that can impact results - like whether the lab tech got enough sleep the night before or a general difference of data interpretation that can occur between two scientists who are interpreting data (maybe the data from one twin was analyzed by lab tech A & the data of the other twin was analyzed by lab tech B) or even from one analysis to another (meaning, if one twin had the same exact data entirely reanalyzed, she might find some differences with her own results) - error in data analysis is the reason science requires replication of results before it is generally accepted within a field; (c) the reality is that these private companies are in the business of making money. Their test results would simply be boring & companies would not get very much DNA testing business if they gave you results based on high confidence interval standards because trying to estimate specific or detailed ethnic approximations just cannot be done highly accurately (as we saw when the twins adjusted the confidence level of one of their tests to 90%). Instead, these tests make best-guess estimates & are sold with the caveat of being for "entertainment purposes" (the same is true for things like personality tests that are commonly sold & advertised to the general population - scientifically sound personality tests are far more extensive, require doctoral level training to be interpreted accurately, & must include a clinical interview to corroborate clinical opinions/interpretation).
My Austrian Ancestry (Salzburger Exulanten) shows up as Balkan. My 1/4 East Prussian Ancestry shows up as East European, Baltic ,and Balkan, and no German, according to Ancestry DNA.
My dad is half Hungarian and between 23&me, ancestry, and my heritage they all have a different combination of German, Eastern Europe, Balkan, Greek(sometimes with and sometimes separate from balkan) and Baltic LOL
I love your program because you keep it real!😀
@GeneaVlogger
I hope you'll do something with the sound levels. I've watched a few of your videos now and the sound levels varies greatly. In some videos I'll need to set my volume to max to hear most of what's being said in the videos you review while your voice is close to the volume of a thunderstorm at a fairly close distance. And again from one video to another for your voice to be at a comfortable volume I need to adjust the sound between 25%-75%.
You do have interesting content and I think your channel can grow alot, but I think at some point issues like this will stagnate growth due to the annoyance of having to adjust the volume settings alot. I'd recommend to increase the volume of the videos you review to be similar to the volume you speak and then to try and make it consistent. I'm sure there's editing tools that can adjust desibel levels to stay the same and that would increase the comfort of watching greatly. Especially to people like me that find it very unpleasant with sudden large changes in sound volume.
Good luck with the future growth of your channel!
Also trying to match the sound volume with the commercials that suddenly pop up. The balance in this video between the reviewed video and you ranting is pretty good, but these damned commercials is like a screaming seagul in my ear.
The computational biologists are basically looking at experimental statistics through a theoretical statistics lens.
If you flip a coin, what are the odds it lands on heads? 1/2 or .5 or 50%
But now, flip that coin 100 times. Theoretically, all things being equal, you should get 50 heads and 50 tails… experimentally, I may get 48 heads and 52 tails and you may get 61 heads and 39 tails.
There’s just a margin of error in everything that’s actively done in the real world VS theoretically done on paper.
We should give these computational biologists some slack though. They’re purely theoreticians… they aren’t the ones performing the actual experiments. And yes, reading DNA is basically an experiment.
I like receiving the updates from my tests it lets me know that they are still researching.
The 1st girl who said “I’m shook!” Her channel is “Hey Hey, Casey Rae”. She’s either in Appalachia or the Foothills of it in either TN or NC can’t remember which one. But she actually travels to visit her dad’s side of the family. She considered her self a “mutt”. Her surprise is real or unreal. It’s been a few years but it’s still good to watch. 😊From the Foothills of Appalachia on the NC side.✌🏻
This video explains why my Native American goes from Indigenous Americus North to Chinese & Vietnamese, Siberian, to Myanmar.
But the fact is they are genetically related and if you look at them they could look very similar. Especially the eyes! By the way if someone is a quarter Native American there are some benefits like in college and stuff. Like free college tuition I 🤔 think... But that will never make up for what they Native American people went through!!! 💜
@@rivkyb7840 wdym because they traded their land and half of them didn't understand what trading was so they wanted it back so the other half of the natives had to fight them with the colonists or do you mean something else?
@@kysisbannable3963 If by "traded their land" you mean "had people flat-out lie about trading agreements and have totally different oral/translated agreements vs written agreements between cultural groups with different approaches to oral vs written tradition" and also sometimes just flat-out conquered land by military force and then pretended it was traded in later history books, sure.
@18:10 thank you for saying that we’re looking for more of genetic family more than ethnicity family when we look into matches.
I believe I watched this shortly after it came out and even in my small consumer brain I could understand not only why there were differences, but also that this was more of a journalist piece to get views than real information.
Basically a journalist/writer needed to come up with an idea to meet a deadline & convinced their twin to do this to as some sort of exposé in order to get views and further their career.
And the ‘recreational science’ dude, he seemed to give off actor vibes. At the very least, he appears to have had an agenda.
Basically, I’ve known about this video for awhile & wrote it off as TMZish or BuzzFeedlike where views are all that really matters.
My 23&Me results were extremely accurate, based on me having an extensive family tree. It is absolutely necessary to have at least one parent to parse results against, because that then ensures the algorithm knows which genes came from which parent per pair of chromosomes. As for matches, I hope one day to know who my paternal line great-grandfather was, via descendants he or others in his family may have had. My most distant match that proved the family tree up that line is a double-11th cousin, once removed, where we share a tiny segment of one chromosome. I am descended of one of three brothers, while she is descended of the other 2 (a 2nd cousin marriage way back when). Interestingly, we also found genealogical relatives based on rare names, like Springsteen, where, though the relationship was proven, there was no DNA in common any more. Bruce is mom's approximately 8th cousin. I hope I find out what my last name should have been before I die, but if people don't test, I never will know, as my great-grandmother was an entire see you next tuesday, taking his identity to her grave.. BTW, my V-22 Y line is almost non-existent in Euro-Americans. It is most common in SW Sudan, 2nd most common up in Cairo. No idea how it got into the Euro context, and the autosomal DNA from dad's side so far hasn't given any amazing clues. We may use the Lazarus program, using my sister's, brother's and my DNA, parsed against mom's, to recreate about 7/8ths of dad via GEDMatch.com. My brother is one of those worry warts, that someone might be able to do something nefarious with our results. Mine are already open for reading in a Cambridge study, minus my name.
Anyway, your content is interesting, Keep it up!.
@ 33:36 I think an analogy of a 16 pack of crayons vs a 72 pack might be fitting, Red vs Brick, Sienna, ect....?
Clearly this video was created to get ignorant people worked up over how the big bad DNA testing companies would dare to take their money and spit out imprecise results. It’s just click bait in the end. As soon as I saw that you were reviewing this video I had to watch, I knew this would be interesting! You’re so logical and intelligent! Which the average person certainly is not. We appreciate you doing the ranting for us.
Thanks for the excellent service. It is hard to navigate genetic data without people that haven't spent some time in a genetics lab. By the way you look like my brother (Perhaps it is from the Sephardic side (us having some Palestinian admixture):)
“...740K snips...” would you explain this piece more in your next video....? ...understand the “margin of error plus complications of analysis...” but maybe drill down more on those ‘dna snips’ for us novices
BTW I appreciate your editorial comments & the way you explain what we are seeing & hearing👌
I have a friend whose family migrated from Albania to Italy centuries ago and then to the USA over a hundred years ago. They identified as Italians when they arrived at New York City, but were they really? Most of us are layered in ethnicities. And that's ok.
I really like the way you put that - "layered in ethnicities". I may need to start using that in my explanations!
That is exactly what many people do not understand. These Albanians could have lived in a mostly Albanian community in Italy for generations and still maintained most of their original Albanian genes. For generations they lived in Italy and considered themselves Italian after a while. That's why you can't trust family stories.
Yes this is what bothers me often when people talk about being this or that. Populations back here in the Old World haven't really stayed always static and 'pure', and I often get weird ethnonationalistic vibes from the way people talk about their genes even if they don't necessarily mean it.
I agree with what your saying. I took an Ancestry test years ago to get an idea of my ethnicity and matches, to then start to do the hard work (paper trail). I now received my My Heritage results to find more of my Eastern European relatives. There is a big difference between the two DNA Companies ethnicity- Ancestry 11 regions, My Heritage 5 regions. I was a bit disappointed ( I do understand the overlapping countries) . My reason for taking the second test was for the breakdown of my matches, as to where they live now and try to find my dads side in others family trees. My grandfather never spoke about his life or his dad’s life back home. Never spoke about other siblings or even what happened to my great-grandmother that never came. A very secretive bunch.
I hated this video so much. Fear mongering is not any form of journalism.
love the rants lol
The percentages are the worst and least accurate of anything on the results.
Honestly, I think what they're looking for without realizing it is really for the companies to have a procedure for tests that are either from twins or that are duplicate tests. E.g. If the DNA from one test is X% similar to another, then issue identical report (or crosscheck, or something like that).
WRT the professor from McGill: they definitely cut what he said to fit the message of the video - in the article that accompanied this video on the CBC Marketplace website, he basically says that he's calling it "recreational science" because the process/analysis hasn't been peer reviewed to a standard he would expect in his field and therefore none of these companies will meet his expectations of rigor (white papers notwithstanding)
For additional information (I'm Canadian): Marketplace reports from the CBC are pretty much exclusively "buyer beware" pieces and always have that dismissive tone regardless of what they are talking about. I generally take them all with a grain of salt.
I love your rants. I have found several distant cousins trough a combination of DNA and building a family tree. These distant cousins gave me photos of my grandfather, great grandfather and gg-grandfather, whom I had never seen before. Too many people think that just passively spitting in a vial is going to tell you everything you want to know.
Also the critics in the video expect the companies to advertise every scientific detail about the test in their commercials or as the first thing on the home page like 1. that isn’t good advertising lol and 2. It would probably confuse beginners and discourage people aka leading to smaller population groups and less room for improvement in the future
Sadly some people are behaving like the Grinch! They should still encourage people to take these test I'm ranting too myself in my room
Yeah I totally agree with you he's only focusing on a portion of the test I agree that people need to take the test I don't want people to be discouraged from taking the test
I have always felt that the ads stress too much on finding your real genetic ancestry. They don't seem to recognize that genetic ancestry is not the same as cultural ancestry. Our family found a cousin in Australia. Turned out Grandpa had a lady friend during the war and now I have a half uncle and cousins in Australia! Way more exciting then my percentage of German genetics.
Jared! Can you do a video about CRI genetics...?
I 100% agree with your rants. To me what you are saying is just common sense. Great reaction video.
FYI: this shows premise is about exposing the behind the scenes of different marketing ploys, and how to stay informed. The show wants to help it's viewers be wise with their purchases which Canadians need bc we are in bad debt. They showed how cellphone companies manipulate their customers to make more money. (Hence why the Canadian government had to get involved to regulate that industry) they exposed the realities of farmers markets, self checkouts, etc.
Thank you for this video, I'm finally starting to understand about the dna results being different. But it would be so assuring to know which testi g company is more correct.
I’m an adoptee who was able to find my bio dad through DNA matches. It’s the most important thing for me.
I come from Ancestry on a small island, can you talk more about how this can change genetic readings.
I have a cousin, 3x over. Lol
I agree, a lot of people don't know or remember that science changes with new evidence and that of course the results will adjust with changes and additions to database and new evidence.
The actual populations that are being compared to themselves are, as yet, an approximation and subject to whatever recent migrations there were. The point is that if I have many cousins in Ireland, it does suggest that at least some of my ancestors came from Ireland.
Wow! That black girl comes from Africa! Who would of ever guessed?
Wow! That is true about the Living DNA about how more in depth for the British Isles. I just found out Ancestry has white paper available now. I found it by accident! I have not tried looking for the white paper for about a year now so I dont know how long it's been on there.
Interesting info. I took the ancestry dna a few years ago and sent the dna data to Myheritage my Negerian DNA were similar, Ancestry being 25% and My Heritage being 31%. The Spanish was 1% in Ancestry and 17% in My Heritage, which was a big difference in percentage. I can see where the spanish comes from being that I have a lot of family from New Orleans and the history there. I also did the Gedmatch and it gave a more break down of my DNA and show the Native American DNA that didn't show up in the Ancestry or Myheritage.
I’ve taken ancestry twice and it’s changed greatly
Same here
You're right that segment was terrible. Nobody in the video brought up the fact that no two people are the same. Even identical twins have different fingerprints.
On Ancestry, twins are identified as “self” or “twin”. In other words, if you took the test twice, Ancestry recognizes that the DNA belongs to a twin or yourself. It’s very close, I even confirmed “anonymous” 2nd & 3rd cousins by their initials.
