🤔 Are all your DNA cousin matches worth researching? 👉🏼 ruclips.net/video/O9tVgFmOxmk/видео.html
Most cousin couples have healthy children.
_But the risks apply primarily to couples who are carriers of disorders that are normally very, very rare, Bittles explained. "For over 90% of cousin marriages, their risk [of having a child with a genetic abnormality] is the same as it is for the general population," he said._
Thanks ❤
The problem is when marrying cousins has been done generation thru generation... the risk for birth defects will be greater.
True
Yeah
you’re right
Is it ok to marry my second cousin sister?
@@Dark-night565Yeah, as long as your family line hasn't done it very often
Here is a question about the effects of a pairing between first cousins.
My spouse has a marriage between first cousins a couple of generations back.
After several miscarriages, we had our DNA tested and my spouses came back with a balanced translocation between chromosome 6 and 16 (non-standard karyotype: 46,XX,t(6;16) (q21;q23)). The interchanged pieces involve portions of the long arm of both chromosomes. The same number of SNPs are present, just some are moved to another chromosome. A sibling also has his translocation. We were fortunate to have a child who has a standard karyotype.
The questions are:
How do the different Autosomal DNA testing companies (Ancestry, 23andMe, etc.) handle the translocation when they process a DNA sample?
How does this affect the DNA Matching results?
I don't know that specifically, but since SNPs are identified because of the adjacent corresponding DNA (which is identical between everyone), I would guess that the end matching results are unaffected.
7th cousins are barely any relation or not something we would call related. You would fit the general public where the risk is about 2%. Entirely unrelated to 7th cousins marrying.
Thanks alot for this education 🎉
I have many Gerhards and Gerhardts in my family tree and they are all from one town that most likely never had more than 350 inhabitants. I don't want to know what may have happened there. :P
Sounds like at least a little mini endogamous population.
My husband has 4 sets of of first cousins marry within 2 generations, then that branch which I am 97% sure is his paternal grandfathers branch are also married into his paternal grandmothers branch and just to make it interesting there are a couple of his maternal grandmothers branch married in for fun.
I am still researching it all and it just gives me a headache, I put it away when I started seeing my family surnames popping up same years and locations.
Sympathies! I'm trying to find a maternal gt grfather- no names to go by - just 4 family names from the right geographic area that keep popping up with the appropriate range of DNA - all of whom married each other, & - frequently! - their cousins - first, second, double..... Some names - back an extra generation- crop up often enough to suggest they're his grandparents, but parents? Large families, of course....roll the 24-sided dice! (So far I seem to share no DNA with any of his other descendants. ) Courage !

My 2nd great grandparents Frank Tilton (1873-1954) and Jenny Clayton (Tilton) (1878-1952) are 7th cousins. I wasn’t that surprised considering that their families are from Monmouth County in NJ and have lived there since the late 1600s. Their most recent common ancestors were John Morford (1623- 1708) and Margaret Morris (1630-1720).
Many families interconnected from small communities. However, it's rare that the couple marrying and having viable offspring for many generations were 1st cousins.
I could never marry my first cousin, our mother's are twins so we share DNA on the level of half-sibling.
That would definitely impact the genetics of your posterity if you did.
My great grandmother's parents were both second cousins, she was their oldest child born in 1896 but they had three more kids despite never getting actually married
To understand better two people are second cousins and make 3 kids?
Families do 'strange' things in genealogical terms.
I'm about to marry my second cousin sister,is it ok?
I know of a case where two first cousins got married. Both parents had weak vision. Their first-born was born virtually blind. They were adamant that it had nothing to do with them being related, and so they had a second child, but it was born with no eyes.
There is no one in the world who you are completely unrelated to.
Fact!
Yea, nice excuse, just don't her pregnant
We all are coming from Adam and Eve
I’m in the uk and really want to marry my Second cousin once removed do I have anything to worry about?
now we are super close with cousins but back then they didnt talk to cousins of opposite sex
I'd be interested to know what the source of this statistic that 80% of marriages in history were between 1st or 2nd cousins. I don't know whether this is skewed to one region or another, or one era or another, but certainly from my ancestry, predominantly in UK and Ireland back to 17th century, cousin marriages were very much in the minority.
what I have found for the most part in my father's family who came from a small rural community in Mississippi was not that they married their cousins but cousins on his maternal side were also related to cousins on his paternal side. For example, my paternal grandfather and his 1st cousin married sisters. That means my father had maternal first cousins who were also his paternal second cousins. They did try not to marry close relatives. My grandmother did have one brother who married their second cousin once removed. both of his children were born with health issues. One son was legally blind and the other son had one leg shorter than which my grandmother believed was because they were cousins.
but the only real issue this causes is when an adopted person who shares your DNA as 2nd to 3rd cousin and you are trying to pin from where. I know she matched my father's side of the family but I do not know how since she matched both his paternal and maternal cousins.
and this set of my father's cousins she matches no closer than she does me so it must not be them
The source usually cited is Robin Fox of Rutgers University. It may be he is the only source because no one else has been interested in researching this area of anthropology/sociology/history.

Additional information for anyone interested.
When cousin marriage is practiced over six generations, the genetic risks continue to compound, further increasing the likelihood of genetic disorders. The inbreeding coefficient becomes significantly higher, leading to a greater probability of inheriting harmful recessive genes.
Understanding the Inbreeding Coefficient
The inbreeding coefficient (F) measures the probability that an individual has two identical alleles at a given locus because of shared ancestry. For first cousins, this coefficient is 0.0625 (6.25%).
Compounding Risks Over Six Generations
First Generation (F1): First-cousin marriage, F = 0.0625 (6.25%).
Second Generation (F2): If children of first cousins marry first cousins, F increases roughly to 0.125 (12.5%).
Third Generation (F3): Continued cousin marriage, F ≈ 0.25 (25%).
Fourth Generation (F4): Further cousin marriage, F ≈ 0.5 (50%).
Fifth Generation (F5): The inbreeding coefficient continues to rise, and can approach but not exceed 1.0 (100%).
Sixth Generation (F6): The coefficient becomes very high, often leading to a critical level of homozygosity for deleterious genes.
Genetic Risks Over Six Generations
Each generation of cousin marriage increases the risk of genetic disorders significantly. Here’s a more detailed look at how risks might escalate:
First Generation:
Risk: 4-6% for genetic disorders.
Second Generation:
Risk: 8-12%.
Third Generation:
Risk: 12-20%.
Fourth Generation:
Risk: 20-30%.
Fifth Generation:
Risk: 30-40%.
Sixth Generation:
Risk: 40-50% or higher.
Key Points
Increased Homozygosity:
The repeated cousin marriage leads to increased homozygosity (having identical alleles at a gene locus), making it more likely for harmful recessive genes to express.
Cumulative Effect:
The cumulative effect of inbreeding over multiple generations significantly increases the risk of recessive genetic disorders, congenital anomalies, and other health issues.
Examples of Potential Disorders
Recessive Genetic Disorders: Disorders like cystic fibrosis, sickle cell anemia, and Tay-Sachs disease.
Congenital Anomalies: Heart defects, neural tube defects, and cleft palate.
Intellectual Disabilities: Various forms of developmental and intellectual disabilities due to genetic abnormalities.
Mitigation Strategies
Genetic Counseling:
Families practicing cousin marriage over multiple generations should seek genetic counseling to assess risks and make informed decisions.
Genetic Testing:
Pre-marital and prenatal genetic testing can help identify potential risks and enable early intervention.
Diversification of Gene Pool:
Marrying outside the family can help diversify the gene pool and reduce the risk of genetic disorders.
Conclusion
The practice of cousin marriage over six generations dramatically increases the genetic risks due to the compounding effects of inbreeding. The inbreeding coefficient rises significantly, leading to a higher probability of inheriting harmful recessive genes and a greater likelihood of genetic disorders. Genetic counseling and testing are crucial to managing and understanding these risks.
I agree that there is nothing wrong genetically with marrying a first cousin today. But I think that taboo came out in the time where first cousins who marring were coming from a set of first cousins who had married and maybe those grandparents were first cousins too. I think then you are more likely to inherit genes from that 5th great grandparent and that could lead to a higher chance of birthdefects. But for the last century at least families have shied away from cousin marriage so I think now there is a lot of 'fresh blood' as far as genealogy playing a factor in birth defects. To use myself as an example; I am a European mutt. I have no pedigree collapse and every branch I can take back to at least 1850. My family has branches that came over any time from the late 1600's to the 1880 and from various places in Europe. If I would marry a hypothetical 1st cousin (my uncles did not have any biological children so hence the hypothetical) that would be a factor. And while I may be unusual with how far back I have gone without finding pedigree collapse in my direct line but I think that there are a number of people who can go 100 years until they find it.. Actually, that makes me think of a question. What is the average number of generations that someone has to go back to find pedigree collapse? If I look at a 6 generation pedigree chart with me a the point there is no collapse. And after that I start having some drop off because they were born in England and immigrated as a family with a young son, not with parents.
Great question, maybe I can put a poll up for people to answer.
This cousin thing is really sad hy because the chemistry between cousins is so strong how close is your cousin from your father's side (example: your father's half sister's child, half sister as in they share a father not a mother) and marrying him how dangerous is it?
Yup, it's a great love for sure. I'm with my first cousin
I absolutely love my female cousins.
My male cousin is married to his father's half sister's daughter meaning that my male cousin father is only half brother to his sister which is the mother of the female cousin bcz their parent's don't share the same father making them half cousins....yikes
@@yezzyr.1499 That about sums up all arguments against it "I was conditioned to think this is icky, can't tell you why though."
There's a few cousin marriages in my tree. :-)
I suspect that's true for any tree going back 4 or 5 generations. - I've got one 1st cousin 3x removed who wasn't content with just marrying her 1st cousin (my 2nd great-uncle), but then went on to marry his brother after she was widowed.

Times were different.

Is it fine if I married my paternal grandmother's sister's son's granddaughter? (I don't know if this relationship is "second cousin once removed")
2nd cousin once removed is correct. It's not really that bad. 3rd-4th cousins or the equivalent thereof produce the most offspring and the healthiest offspring.
You could marry anyone as long as their not close relatives.. 1st cousins are like boarder line of being okay and after that like 2nd 3rd 4th it doesn’t matter, your able to marry …
I’ve been in love with my cousin for most of my life and I’ve stayed away from her and did not persue our attraction .
Probably a good idea.
Ngl, life is a bitch.
What about 1st cousins once removed? Would there be anything to worry about genetically in that situation?
I wouldn't lose sleep over it.
@@FamilyHistoryFanatics Can you please do a video about FCOR please? There's a lot of taboo and misinformation that needs to be weeded out. It would be so helpful to get your educated opinion.
I have a serious Questions
My Mother's Grandmother and She's Father's Grandmother same can I Merry with Her or not ?
Answers me Plz
So I was given a choice to marry one of my cousin in an arranged marriage a couple years ago. My parents are 1st cousins and her parents are 1st cousins. Her mother and my mother are sisters and her father and my father are 1st cousins. Because of the high genetic risk for birth defect I declined to marry her and married someone outside my family. So would the risk be more than 4 percent and also how much dna do I share with her seeing how cousins usually share 12.5 percent of their dna?
There would be a higher risk since both sets of parents are also related. This is the type of dynastic marriages within the royalty of Europe that made certain genetic characteristics prominent over several generations.
@@FamilyHistoryFanatics would he share significantly more DNA due to this.
I believe you made the right choice. You would share more than 12%. Probably more like brother and sister 30 or 40!
Yeah I believe so as well now. It was best for the both of us. My cousin got engaged to someone else now and we are both happy.
@Saad Usnam
I think people should get married for love (even if it's a cousin) not an arranged marriage. I'm glad you and her are happy with your life!
Hi, I support cousin marriages! I'd like to know if there is an organization to help spread the good news that cousins can marry without it being discouraged in societies in our cultures. Second, since the only issue is that of genetic inheritance, is there a genetic test that is encouraged for first cousin? In reality, most couples that are not related don't test for this and they do pass down genetic disorders or diseases. Can you imagine how cruel it is to not marry someone because they have diabetes or cancer? When you love someone, you love that person "in sickness and in health."
I can not help you advocate for or against such marriages. There are no tests that I'm aware that will predict the genetic inheritance of children of two persons, regardless of closeness of relationship.
@Itagaki Rihito Supremacy right! It's like comparing animals to humans. Wait, that's what society is becoming. Bunch of filthy animal's.
My 8th Great Grandparents are cousins
Mary (Briggs) Studley's (1707-1797) Great Grandfather and Eliab Studley's (1706-1785) Great Grandmother are Brother and Sister. They are Joseph Tilden and Mary (Tilden) Lapham she married to the family's servant.
That far distant is not going to show up in your current DNA makeup. In fact it is even possible that you didn't inherit DNA from either of them.
so touching for an excellent video
Thank you very much!
When you say your brothers got the red-hair gene, do you know that by testing or they have red hair? If they do, wouldn't that mean your father was also a carrier? Therefore you know you didn't get both but you have a 2/3 chance you got one copy from either your mother or your father and could therefore pass it on to your children. Is that right?
By testing. Same with knowing that my Dad doesn't have it. I've tested and know that I don't have a copy of the gene as well.
I Am married to my 3rd couisn. My great grandmother and his Grandmother are sisters. We did not grown up together but our families did know one another .
Hi. I’m so confused. What are the children of my cousins? Bearing in mind my grandfather married two women. And these cousins have a different grandma to me. What relation are their kids to me? Is it second cousin? Or 1st once removed? Is there such thing as half? I mean we have half siblings right.
Half first cousin once removed. Half because you only share one of your grandparents, Once removed because they are the children of your 1st cousin.
Hello, what would my parents first cousins grandchild be to me? Because I’m really not sure. Thank you
Your 2nd cousin- once removed.
Jason has you covered.
I am married to my first cousin from both paternal and maternal side. We don't have any children since 4 years. I've had 4 misscarriages and 2 D&C.
I'm sorry to hear that.
Please don't judge... I've had a crush on my cousin for a long time. We don't see each other very often. Only about once a year. We keep in touch a lot and we play online video games together all the time. Idk if I'd ever say anything. The thing is society frowns on it so much that you'd be outcasts if you did make a move on your cousin. We both have a lot on common. Neither one of us likes kids. We're not really interested in ever having kids. So, geneticist wouldn't be and issue. It's more of being and outcast thing...
ohh damn
I can't help you with that. Sorry.
Tell her dude. She’s probably waiting for you to say something 👌🏽
Gross. Imagine how your guy's parents would feel knowing that their child are f#"$"
Did you married her! Brother... I too hv same situation 😃 ....I just want to Marry her because I don't want to Let her Go...we share strong Bond and in Relationship for last 9 Years! I don't believe in own a kid biologically only... Current Population is enough....we can Adopt a Child from Orphanage if Pa na Mom needed!
I really don't know whether I Should marry my maternal Uncle's daughter. She is my first cousin, her parents are unrelated and our grandparents are unrelated. My father married my his first cousin's daughter and my paternal grandparents were first cousins. What are your thoughts in terms of birth defects and is there an increased risk of mood behaviour disorders? She is also 18 and I'm 30.
Ask God what you should do and let that answer be your guide.
Find a genetic Counselor in your area and 18 is a bit young.
Trust God and his commandments if you are a believer otherwise know that even a random accident on the road can take your life
Me and my husband are cousins (paternal cousin) my sister is married outside family tree ( not related) can my son marry my sister's daughter without having any genetic disorders in kids...
Is it possible to not have genetic disorders - yes. There is just a higher probability that they will. Going from 2% to 4% is doubling the probability, but the probability is still relatively low.
Hey! Hi Neelo.....i want to know more about you...of you are active on This Platform please do reply! I want to Marry my paternal Cousin and want to discuss it with family!
I think you’re too quick to dismiss the dangers of marrying a cousin. I think anyone contemplating marrying a cousin should go for genetic counselling, though a one-off situation is probably not a great danger, however, some communities inter-marry a great deal. Communities that practice cousin marriage have higher numbers of children with inherited conditions. Here in the UK, the Pakistani origin community has the highest level of cousin marriage and a higher proportion of children with inherited conditions. Because you have people who are the products of cousin marriages going on to marry cousins themselves.
"Product of" 🙄
Ya that’s bc they keep doing it for generations and generations. Like he said the more the family did it the more likely if u do it too that ur baby will have issues. But if it’s not in your family then most likely you’ll be fine
What do you think of the Dr.Phil episode where they paint it as a much higher risk? Her numbers seemed WAY of with 80% chance of miscarriage. Especially when ive seen so many people commenting on forums and groups of cousin couples in their family.
Depends on where the 80% chance of miscarriage stat is coming from. About 25% of known pregnancies end in miscarriage, but unknown pregnancies based on statistical analysis end in miscarriage at much higher rates (no definitive numbers are given in this paper, but based on the statistical analysis miscarriage rates may be as high as 70 or 80% www.biorxiv.org/content/10.1101/372193v1.full)
She claimed cousin marriage results in 80% miscarriage. Thanks for your reply :)
Actually I'm not sure where those numbers come from. There is actually a higher number of live births between cousins than non related people. So she may have had the miscarriages thing reversed. Or they are defining miscarriage a strange way.
It is a higher risk
I believe third cousin marriages are optimal as far as the highest genetic compatibility while having the least amount of danger of inbreeding bad recessive genes.
I heard that too. Can you give me a source?
Second or more, research says that having kids with your second cousin is almost the same marrying a strangers genetic wise
It's the Iceland study since they recorded damn near everything. 3rd and 4th cousins reproduced much healthier and were said to have less miscarriages from the mothers immune system simply micecrafting the baby from the womb. There is such a thing as going too far and we've hit. It probably explains a significant reason for social breakdowns.
Second cousin may be okk if they have different feeling but first cousin NOPE they r like half brother for me
Should I be worried about the judgement I will face if I choose to marry my first cousin? Do you think that if I do so, I will face a lot?
Depends where you're from
Play russian roulette at your own risk lol Children of first-cousin marriages have an increased risk of autosomal recessive genetic disorders, and this risk is higher in populations that are already highly ethnically similar. Children of more distantly related cousins have less risk of these disorders.
Nobody will ever thing it's okay or "normal". But who's gonna stop you?
Hi sir, so if the first cousin marry eather and their father are sibling, that will be ok for the childrend of that couple?
Most likely.
@@FamilyHistoryFanatics can u pls msg me sir
Is it save to have children with a half cousin? We share only the same grandfather since he had 3 wifes.
Lets say with wife 1 he made my father and with wife 2 my half aunt (half sister of my father). Which would make us half cousin with a DNA share of 6.25%.
Also, is the DNA of male more dominant somehow in genetic?
Something new didn't know thank you
you're welcome
What is the result should show that 1st cousin safe to have kids?
what if i'll married my 3rd cuosin?. what is a posible , may happen in our baby?.
there's always a chance that your genetics will pass down negative mutations. However, as explained in the video, it's the more closely related relatives that have more genetic issues in their off spring.
2% for everyday couples that are strangers & 4% for 3rd Cousins. That means that your kid will have a 98% chance to be absolutely normal vs 96% with 3rd cousin. That is hardly a difference stats wise!
We're almost 5 years in relationship with my 2nd cousin. Is there any problems if we will continue this? We're scared for our future baby,. We loved each other and we're happy for each other being together,,
Please give some advice.. Thank you so much!
go ahead.. You are not wrong..
There is no problem with your baby but some people who allow guy marriage says worry about it. I says they are only disturbing your mind, after disturbing your mind Problem can gain there is no matter who is she except real sister. I advise you positive 100 percent. There is a lot of problems with babies and their parents does not belong to cousin marriage. Did you understand.
@@havealookheretoo898 thank you😊
@Queen Ui
2nd cousins share around 3% Dna. The risk for a child is about the same as strangers. Although even normal couples have a risk. There is no 100%
@@anow5084 the risks for brith defects is actually slightly higher for 2nd cousins. From 3% that all couples have to 3.5% for second cousin couples. AGAIN not a significant increase but still an increase
When you have a chance, would you explain how sibling-sibling incest affects DNA matching in a family, among cousins? For instance, would children and grandchildren of such a pairing share 50% more DNA with cousins descended from one of the incestuous partners by another partner and 33% more with descendants of the incestuous siblings' siblings? Thank you.
I'm not going to cover that topic as it's too narrow for the interests of this channel.
Well for me and my cousin are only related by a grandmother🙄
His mother and my father has different fathers...
So that's why he has always said we were barely related.Question is if I do this would I be wrong☹️
Only you can decide if it is wrong. The question you have to ask is whether your offspring would be negatively affected by not having more diverse DNA.
@@FamilyHistoryFanatics Exactly and the reason why I didn't do it. Then I turned him down. I thought about the offspring stuff and. I was like it's not worth it 🤣 He really seduced me at 20 and I decided hell no at 29 I cut it off. I'm 30 now on to bigger better things
Same situation happen to my cousin. This is what it means to be half cousin's. Imagine how your parent's would feel to know that their child is with its cousin. Cause even though your parents don't share the same father, it don't mean that there's no bond... for crying out loud... they still siblings...
I did a research paper on cousin marriages in high school. I am fine with it.
It causes extreme right-wing beliefs by making people only care about their own family (their own kinship group). Hence, cousin marriage causes corruption, animal cruelty, racism, homophobia, sexism, ecological destruction indifference, an IQ drop of at least 10 points, lower Openness to Experience (hence fewer Nobel Prizes in the sciences due to fewer people possessing intellectual curiosity).
@Moondog you're full of bull shit, that is apparent
@@moondog7694 if slippery slope was a comment
@@moondog7694 haahhahaaahahahha wtf
I’m more interested in how much the risk increases if it’s practised again in the next generation, let’s say a child of a first cousin couple also marries there first cousin (not double first cousin). Would the risk increase by a further 1-2% or does the risk start increasing exponentially?
@@arronwilliams9795 I saw another study where the risk of first cousin for repeated generations (3 generations of first cousin marriage etc), the risk trebled to 7.5%. But that still seems very low considering how much we have been told how bad it is. I guess in the general population first cousin marriage is not a big concern at all, however if you’re family has some bad genes then the risk is far greater.
@@asfand5747Family history does matter, yes. Regardless, as long as people think it's like a 70% increase they will never even debate it. Their only reaction is to say it's gross because that's how they've been conditioned.

I can not council you on the should. Genetically, second cousins are better to create life with than first cousins.

is it fine to marry my fathers cousin's daughter but at the same time im not sure if my father's cousin is his cousin or how far they are

There are always risks. For third cousins, the increase in risk is so small that I wouldn't lose sleep over it.

Not even a concern at all. I did 23 and me. I have so many 3rd cousins I've never heard of (1000's) around the world I could have married one of them and maybe never figured it out!
The risk for a 3rd cousin is the same as any random person you may meet and have children with.
dangit does that mean my kids wont have blue eyes from me? (i have brown eyes) but both of my parents eyes are blue
It depends. I have five children with my wife. She has brown/hazel eyes. I have green eyes. Each of our children have different colored eyes - gray, dark blue, green/hazel, brown, medium blue.

@@FamilyHistoryFanatics plz I wnt to know. I am in love with him. I don't wanna loose him.
@@FamilyHistoryFanatics is there anything that can be done to avoid defects
My father married to his 2nd cousin... I m normal bt my younger brother is handicap by leg.... And the destiny is my 2nd cousin fel in love with me?😑 What to do?
F@ck the world. If she love you you marry her
Run!!😂
2nd Cousins are usually no problem. Your younger brother's condition may not be because of the close relationship between your parents.
@@FamilyHistoryFanatics will think futher & tell my decision to u sir..!! Thank u for reply!!!!
To each is own do what makes u happy there is alot of things going on in this world isn't right but it still exists.same sex marriage isnt right but then again is what u like and who u want to be with
I don't weigh in on the morality of marrying a cousin. Only the genetic implications.
Meemaw said ain’t nothin wrong with marrying cousin Sally.
Then have at it
I cannot imagine marrying my first cousin .
Marry me then.
Yeah marry him
Lol
How does it feel??
@@jeralynserato3675 To the kid that gets born with genetic faults. It feels like hell. Painful Agony.
I'm about to marry my second cousin sister,so is it bad?
No
How about third cousin? Will it affect the DNA of the baby?
Not likely.
My parents has the same GGM and I really feel some kind of way 🤦🏾♀️ this was in the 1970's they knew better it's not like they didnt know each other like seriously 🙄🤨🤔 I also have a lot of different races in my family tree I really didnt know that until I did the family tree thing I always knew that I was a maloto but not to this fact 😑🤔
What about First cousin once removed (FCOR) marriages? These are common in South India.
That's still rather close for genetic inheritance purposes.
@@FamilyHistoryFanatics If her grandmother and my dad are siblings, is this union forbidden/ likely incestous? Please reply. Thanks for the earlier response.
Can you tell marrying my first cousin OK?
My mom's sister's daughter?
@Alia Rai Are there any medical test to check if it can happen in future?
I think opposites attract is based on the phenomenon of not sharing two recessive genes. In other words, if you're attracted to your cousin, theres probably a good chance you are not going to have mongoloids as my parents used to say.
The opposite is true. Sharing things in common is true. It is very likely teo siblings that never got to meet until later in life start romantic relations. 3rd and 4th cousins have been shown to have the healthiest offspring with the most grand children. Expect to see more miscarriages as people lose their minds over avoiding even 5th cousins. We are all cousins.
Hi Family History, I have ordered AncestryDNA Kit and I'm wondering is it possible to take the required amount of saliva from 2 years old kid? What is the minimum amount needed to perform the test and is there any other materials they accept like hair? I did not open it yet and if it not possible then I'm going to return the kit.
Thanks.
For Ancestry and 23andMe, the kid needs to be able to spit. I've had a 6 year old do it but haven't tried with a 2 year old. Its not a lot of spit, probably about 10 good spits. Family Tree and MyHeritage use a cheek swab which would be easier to get from a small child.
No one accepts hair.
My family says i should marry my cousin who was result of a cousin marriage herself
We might match but im worried a little
Also i dont like my genes, our shared grandfather passed me gynaecomastia and curved nech genes
Could have been worse, like cancer or something but still, i dont want my children to be like that
Is there a blood test cousins or not
Genetic testing
So i can marry my first cousin my mothers sister daughter..?
You can marry anyone that your country's laws allow. The question to consider is whether this would be detrimental to your offspring or not.
So i can marry my father's brother's daughter right ? please replyyyyyyyyy
You can do whatever you want. There is some cautions about procreating.
Can I marry my grandfather sisters daughter daughter?
Your second cousin, you would have to ask her.
Everyone wants to focus on the genetics, but the social and political and economic ramifications may be important drivers of the modern taboo.
How bad it would be if double first cousins had child together?
Socially, probably a little awkward. Genetically, probably not bad but worse than if unrelated people had children.
OKAY SO, its this girl i like, my grandfather and her grandmother are cousins, i think are 2nd or 3rd cousins , what does that make me and her??????
4th or 5th cousins.
@@FamilyHistoryFanatics omg THANK YOU
@@FamilyHistoryFanatics do you think its okay to date her?
@@thetreepeople7001 in my eyes, no! Mostly bcs of moral principles, but genetically it isn't a huge deal i guess. I
Thank you for this video,
I want to ask What do you think of the marriage of "double" cousins (cousins whose fathers are brothers and mothers are sisters)?
I don't think anything of it from a moral stand point. However, a person marrying their double first cousin will definitely run the risk of negatively impacting the genetic code of their offspring similar to what I said in this video.
So my grandparents were first cousins. I took a DNA test because my dad has a child somewhere that I'm trying to find. My half aunt comes up as a first cousins for ancestry so I'm having a hard time figuring out how my half sibling would come up and what to look for and how to tell 😂
A half sibling shares around 1700 cM. But in your case, with your paternal grandparents being 1st cousins, you would expect more shared DNA, around 2000 cM. But the range is probably between 1600 and 2400. So there is some overlap between normal half siblings and full siblings. It is probably going to be reported as an aunt/uncle, grandparent, or grandchild, and possibly a sibling.
@@FamilyHistoryFanatics thank you so much for replying back!!
Is there any additional risk for 2nd cousins?
There's always a risk, but it's lower than closer relatives.
@@FamilyHistoryFanatics is it higher than a random stranger?
yeah and how about 3rd cousin 🙏🏻?
is it equal with stranger too ?
What’s the mega base length of a second cousin? In terms of roh
Well if a cousins get married a dad can’t run away imagine Christmas dear god
Interesting comment. Thanks?!?
I’m in love ❤ with my first cousin from my mums side my mums sisters daughter
this explains my anorexia djhfsdjgda
Are you sure that 4th generations has no problem? In know that until 7th generation you still have risk; and it happend to a cousin of mine ; she lost both of her children with this genetic desorder; according to the diagnosis this was because they were related;
There is always still a remote chance of inheriting genetic disorders from that far back, but her situation is likely a combination of factors.
How about my moms third cousins son
That would be your 4th cousin. You are probably not going to run into any genetic problems from that.
Is my 5th cousin boold ?
Typically
I've been observing/ reading some comments throughout this video and some are really trying normalize being okay with marrying cousins. Those that are okay with marrying a cousin are also in the same situation. I just don't understand why they are trying to normalize it? I doubt it was love that got that person Desiring its cousin. That's not love. That's lust. So many 🐈 and 🍆 so why put yourself/future kids & family in such a nasty predicament. Where's your morals & values? Makes since if you aint got That or wasnt ever taught from what's right to wrong.. BUT Don't do this. Trust me, it's not worth it and even though you might come to terms about not giving a damn, you will. It will hunt you & other's will never find it okay & neither should you be okay with it.
I don't address whether marrying this person or that person is normal, acceptable, etc. I just focus on what happens genetically for the purposes of genetic genealogy research. I'll leave the moral and ethnical discussions for someone else.
Look brother.... I don't know your thought process but here in India (Southern Part) there are 25-40% marriages are between Cousin including Paternal and Maternal....and yeah there is some risks of genetic disorder but believe me..... I have met many husband and Wife who are cousins and have children and they are living happily....yeah got few on count 9 out of 252 people who have children with defective genes. And Love isn't bind within Lust Only! We have sex sometimes, in a month or two but we love and understand each other than other people....Love is just part of Life... It isn't life only....we are in relationship for more than 9 year but never think like you made statement here...like we are together only because of lust...may be its your thought process about love and marriage!
I too want to Marry my Cousin and not for fear but with understanding that we don't want children...and if we would, then first we will get check-ups done after that... otherwise we can Adopt children from Orphanage, there are lots of childrens who needs Parents to look upon!
want to marry my first cousin
Are you free to do so?
