The Man Who Discovered Dominant & Recessive Genes: Meet Gregor Mendel
HTML-код
- Опубликовано: 28 май 2024
- Introducing Gregor Mendel, the Austrian monk who, with the help of a garden full of pea plants, discovered the concept of dominant and recessive genes and paved the way for modern genetics. We'll also dig up the dirt on a scientific scandal that has followed Mendel beyond the grave in this fun new episode of SciShow, hosted by Hank Green!

Bruh, how is this video so old? It’s so good animated. I bet the person that edited this video is god at editing now.
I guess the editor had somehow few genetic trait of Mendel, I mean ' ahead of his time '!
My bio teacher needs to watch some of your videos. She took an entire 3 hour class to explain Mendels work and why it was important. Thanks Hank!
Why did Gregor Mendel fail handwriting? He kept crossing his peas...
Sorry? I didn't understand..
+Marcus Christianson uhhhh... I hope bad pun makers like you are slowly bred out of the gene pool......uhh....
Of course I'm kidding that's actually really mean.
LOL, puns are mazing, ur awesome bro... took me a few seconds to get it tho tbh.
Marcus Christianson I don’t get it
ha, funny.
I refuse to believe this video is eight years old.
I agree
Why?
@@sum1sw because that would make me feel really young
No it’s 9 years
it,s eight
Gregor Mendel was my hero as a young junior high school science fair kid. I won the science fair based on his work (via hamsters, fastest breeding mammals I could find and my mother would tolerate). Thanks, Herr Mendel! :-)
😮
Mendel's dedication to an 8 year old experiment all by himself is amazing
Lysenko > Mendel
@@comradebanana129 The heckin what? Lysenko, the father of killing millions by being wrong about ag science while insisting (through the iron fist of the soviet state) that you're right? The closest thing to being right he ever was is when epiginetics proved he wasn't quite as wrong as it first appeared (while still being very very wrong.). To put it another way: Where he "was right he was not original, and where he was original he wasn't right"
whos watching in 2021, 9 years after it was made!
Just because it is 9 years old doesn't mean it has value. Think of all the great music that is 9 years old or older...
me
i am :)
Me watching in 2021
Me :D
I swear this explained 20 pages in my book in 10 minutes. This isn't skill, this is talent.
I really like Hank's style of humour.
noooooooo this came out 2 days after my bio final. Mendel was one of the things we learned a lot about.
Same this came out one day before my Gregor Mendel test but I got an A+
How long does it take a pea plant to flower? His experiments must have been very tedious; patience is definitely a trait of a great mind.
Damn straight, as Hank said he spent 8 years cultivating them. What I find most impressive is that If you look at any of his data you'll see that for most of that time he was literally just doing the exact same experiments over and over again to get more accurate results. For some of his tests he recorded nearly *8,000* offspring to get an accurate ratio of green:yellow. crazy patience.
I really regret taking Mendel Lightly.. when i first studied About him back in Grade 10 not much was written about him.. But i just came to realise the true extent of his brilliance and Perseverance. Mendel is not the father of genetics only for His Brainwork but also because of his incredible patience and hardwork.. Mendel was truly Overpowered...
"and no I'm not going to shut up about pea plants; it's fascinating!" Haha! Hank is awesome.
Can you also do Dimitri Mendeleev, father of the periodic table? His story is just genius!
My teacher made me watch this :/
same 😆

Same.
Gregor Mendel was an Austrian monk who was considered the father of modern genetics. And researched pea plants.He was born in jul 20, 1822 and sadley passed away in Jan 06, 1884 at the yung age of 61 years old
Gregor Mendel as a child and teen spoke German and his parents were very poor but he lived on a farm so they did have plenty of food to eat . When he grew up his parents wanted him to work on the farm but he went to a college. And later studied peas and he discovered that there are 7 basic characters of 20,000 individual pea plants and in 1865 he published a book on peas and gardening. He was also a very religious man
Mendel discovered alot of things about pea plants. He discovered genetics are hereditary by experimenting on his parents farm. He dicovered that plants have dominant and recissive genes and these determine the plants traits.Mr.Greager also found that purple flowered pea plants gene is more dominant.
Mendels parients spent a lot a lot of money on young Greagers education. Mr.Greagers peers dident even understand his discoveries untell 35 after his death they started to understand his confusing work. Mendel did so many experiments he was considered the father of modern genetics.
I'm so glad this video exists! I have to talk about Mendel to a group of classmates tomorrow and I'm finding his writings hard to understand. This has helped greatly!
DUDE, This show is great! I love the attitude and love the style. Keep up the good work.
great minds: Hank Green

we have an episode on Nikola Tesla in the works - it's scheduled to be published in October. so, feel free to keep requesting him, but we've heard you! you just have to wait a little longer. our production schedule prevents us from doing a super quick turn around on Great Minds episodes.
THANK YOU FOR UPLOADING THIS! I have a final including all of this information tomorrow...
Thanks Hank! Great job on this video :) It makes everything really clear and straight forward.
Please do a segment about American biochemists Carl Cori and Gerty Cori, they practically revolutionized our knowledge of carbohydrate metabolism
my teacher showed this to us, and does NOT appreciate your cursing
lol press f to pay respects

I would love to hear more about things along the lines of Psychology and Neuroscience. The various studies, famous minds, origins, importance in today's society, etc. Anything a Psych 1010 course would touch base on, but never delved into those fascinating details. I want to know more about Pavlov, Maslow, Skinner. The different Neurological and Psychological disorders like OCD, ADD, depression, phobias, the works! Your show is my favorite and I can't wait to see more!
Great job on this episode!!! BTW, I went to Mendel High School in Chicago many many moons ago. Love this channel.
The scandal wasn't as juicy as I thought.
a sheer disappointment that was
what was the scandel
just discovered your channel,greetings from brno,czech republic.
A to mu Dovolite tvrdit že Brno je v Rakousku? Když už tak v tè době v Rakousku - Uhersku
@@Mirinovic Rakousko-Uhersko vzniklo až v roce 1867, ve videem zmiňovaném roce 1843 šlo skutečně o Rakouské císařství (tedy zkráceně Rakousko). Opravdu si nemyslím, že se Hank snažil říct, že Brno je součástí dnešního Rakouska.
@@prokopdvere4004
Brno i za Rakouska bylo na Moravě, to sem chtěl říci A díky za slušný argument.
guys... nobody will probably read this, but i just want to make this clear. Im from the czech republic, and what was then austria is not possible to put in connectin with what is austria now. austria then would be better to as an habsburk monarchy. it included what is now austria, as well as buch of other historical countries, like bohemia and hungary, and brno, was and is a capital city of moravia. people living there would not consider themseves to be austrians, but to be moravians. ( as they are still now, when they brag about brno, and talk crap about prague, and stuff ) so, you could say, that it was a part of austria, but it is inaccurate, and most of people would not get it right.. bohemians never thought about them selves as about austrians, really, never. they consider them selves to be bohemians, which was part of habsburk ( austrian ) monarchy. in fact, they would be very insulted if you would call them austrians, because they actually hated vienna, and austrians ( meaning people of historical realm of austria ) so to say that his father was austrian worker would probably really disturb him.
no one cares...
shuttup, you dumbfuck
ok cool thanks
hey shutt the fuck up shuck face
+ WATCH YOUR MECHANICS( CAPITALIZATION) DUMB SHUCK!
i have a hanging basket of peas with white flowers! I've been using Laxton's progress variety. I actually wanted to play with pea breeding because of Gregor Mendel's work. I've also got bush cucumber in the same basket as well as parsley.
I love you Hank. You are so super cool. Yes, I mean it!
i would love to see a Sci show great minds episode on srinivas ramanujan
What a mathematitian!
FYI .. Hank: you are a genius and wonderful teacher, and we love you. ... Great episode, thank you.
Aaah!! Hank! I said you should do Mendel like weeks ago! I'm so excited!!
ver-sook-uh oober flonzen hib-rid-en.
Two important things to remember when pronouncing German words: 1) EVERY letter, including vowels at the end of words, are pronounced. An E at the end of the word just has the "uh" sound to it. 2) ......Unless there are two vowels next to each other, in which case the "first one walk and the second one talks". So, in the word fleisch, the ei makes the I sound. In the word tier, the ie makes the E sound. This is true in almost every case except for vowels with umlauts next to other vowels, in which case the pronunciation is probably something ridiculous. Speaking of umlauts (the two dots on top of a vowel), that just means you pronounce the vowel with its long sound and not its short sound. German lesson complete. Have a good day.
This may be a bit late but what do you mean by vowels with umlauts next to other vowels? Umlauts are basically shortened versions of "ae", "oe" and "ue". The version with the two dots is a relatively new invention. The only thing common in the German language of what you are describing is "äu" which is basically the same as "eu" :)
And they put down thier beakers and said, "ooooohhhhhhhhh."
4:19 the way you say number two makes you sound like Eugene from tangled
this is what i would have needed to ace my ap biology final last January. so darn good videos!
Norman Borlaug!
And I'll take the bag of whiskers, thank you very much. :P
This dude is like a sciencey version of Tobuscus.
but funny
lol thats what i thought
me to
Thanks guys for the support
Man I'm seeing this now as a grade 8 student and this person really has the knowledge of Sheldon! 😳😲
Absolutely inspirational video, thanks for posting #MENDELTILLIDIE

Can't beat him, gotta love a bit of Gregor #MentalMendal
Who Is Here From School Science Class???

Hi Hank. Thanks for the show! I'm really digging this 'Great Minds' series. Have you and your team considered doing a broader version...sort of a History of Ideas type of thing encorporating science, art, and philosophy? (Yeah, I know...way too narrow a scope for a series ;))
In every course I took that asked to research or wright or talk about a famous person of history, I to this day still declare that Otto Van Bismark of Prussia is by far one of the most fascinating minds of history in his brilliant manipulation of the international treaties and under-the-table dealings and treaties. I would like it if you, in your most entertaining of ways, shared the wealth of Otto Van Bismark of Prussia to the rest of the RUclips Community you have following you :) Thank you!
I don´t know, it just poped up in my head :D
Dont take me serius...
Isaac Newton: Great Minds? Discover laws of gravity, motion, optic and calculus before he turned 26? And how his religiousity get the better of his scientific inquiry... such a lost.
nventions were copied from liebnitz
madmarvin99
i think its the other way around.
KagirinaiYonaka xorry no, liebnitz was the real inventor of many of these , newton wasnt able provide complete proof for his 3 laws of motion
no, newton provided a comprohensive proof for his three laws.
and fyi, liebnitz was also a heavily devout christian as were newton. I don't see why these two things are antagonistic to one another?
I have been to his growing site and museum in the Czech Republic. Its really cool.
So, I think the underlying workings of computers and computation would be a cool thing to put on Sci-showsee, most people don't understand a few basic things...I think a general grasp can be given pretty easily, and you'd do it the most entertaining Hank!
1.) Binary Numbers (maybe compliment of twos, cuz it's awesome)
2.) Digital logic: (How you make and gates and or gates out of switches, how you make more complicated things out of those....that's really all you'd need to get people to know!)
I need to pea
this show is hilarious
Hank, thanks for such a great lesson, but I wish you had gone more into the details of how tedious his experiments were. He had to manually keep the pea plants from being pollinated and had to manually do the pollination in addition to all of the data collection. I learned about it from a kids book "Gregor Mendel : the friar who grew peas".
"Mendel put us all on the right track." Well put.
I want the bag of shaved whiskers!!
XD
xD
u talk fast, super fast
Wentzel van der Berg Mendel is my ancestor
Tycho Brahe would make an AMAZING great minds clip. A huge contributor to astronomy and the ultimate mad scientist.
I know this video about Gregor Mendel, but I now have a new favorite word. "Kerfuffle". Awesome!
I feel happy that God supported evolution and genetics. Also, I'm Roman Catholic Deist! ;)
i learn more about life in scishow then school. keep it up Hank!
i'm glad you're funny. i love watching these
thanks for this, I have a school project on genetics right now!
Could you please make a video explaining what makes certain genes dominant? As in what physical difference exists between dominant and recessive gene segments that would explain the way they interact.
Do one about Hank Green, he is a genius when it comes to education!
Just perfect video, thank you so much :-)
Thanks for this video, it has made me excited for my Biology course which I will soon be studying :D
That makes sense now, thank you for explaining it.
Yep I knew all of that. Nice to watch one of these and know all of it. Makes me feelz brainie. Also nice for my memory to be refreshed. I remember my teacher going on and on about all the controversy. I found it interesting, many others didn't... :(
Super interesting! Thank you 😁
This was wonderfully narrirated!! cutos
Congrats, great video.
Do one about William Ferrel! He's an extremely under-appreciated genius. Born on a farm in the early 19th century, he had a very limited education, mostly self taught. But at a young age he already began predicting lunar eclipses and stuff just by doing math with a stick on his barn door. Later, he started explaining the dynamics of our atmosphere and found an error in a work published more than 200 years earlier, and now he has an entire atmospheric cell named after him.
Much Appreciated
MY GOD hes good at editing good info too.
i saw some suggestions for Nichola Tesla, and that sounds awesome. Please do one episode on him.
Excellent!
Hi, great video on Mendel. Have you done one on Johannes Kepler? Would love to see one.
Thanks Hank!
The dominant vs recessive thing is about alleles for a gene, which are different versions of the same gene. I don't think we really know why one allele is dominant over another. The difference between dominant and recessive alleles can be as little as 1 DNA base sometimes. But there are also other interactions like codominance and incomplete dominance, where neither allele is fully dominant or recessive, or the black squirell + white squirell really does make a gray squirell (as an example).
As a computing student I say Alan Turing, a lot of modern computing is based on his work and this year two of his papers were declassified which shows how ahead of his time his work was if the military were still finding it useful. Also his death is a very sad story and it's a part which most WW2 history programs don't mention.
This is an amazing video,only a little minor thing, Brno was never in Austria. At the time, Czech Republic was a largely self-dependent part of Austrian-Hungarian Empire,but it's a bit like saying England when you mean Scotland,you see...
Yes, there are lots of them. Bruce DePalma, Stan Meyer, Marko Rodin, Paul Pantone, Dr. B. Stanley Pons, Dr. Martin Fleischman, the list goes on and on. Just because we don't understand what or how they do what they do doesn't mean they are wrong or crazy.
We'd like to see an episode about Karl Wilhelm von Nageli. Thanks so much!
Hey there! I would love to show this to class but totally need a transcript. Now when I hit the transcript button above (the one next to the 'add to' button) I get a rough transcript but with many many wrong words. Is there a good transcript available for a student in my class who cannot hear before I start typing the whole thing up?
Do an episode on Konstantin Tsiolkovsky. He was a weird russian cosmist philosopher who eventually ended up influencing the soviet space program.
You can do an episode on the whole russian cosmist movement, they were highly influential and mindblowingly bizzare (and they were great scientists). Nikolai Fyodorovich Fyodorov was nown as "russian Socrates", Vladimir Vernadsky introduced this notion of noosphere, et cetera.
I think you should talk about Anna Morandi Manzolini & her contributions to medicine and the study of human anatomy in 18th century Italy. She wasn't an experimental scientist; she made incredibly detailed wax models of the human body and its parts (specializing in sensory organs and the male reproductive system) for doctors to study. Rebecca Messbarger's book "The Lady Anatomist" is a good starting point.
already done good sir.
Hi, have you done a great minds video on Johannes Kepler? I'd love to see one.
Ahmed Zewail: Great mind. And, i would like if you include that he, as Galileo, did introduce us to a world that we've never thought that exploring will be possible one day; the world of the small, and very fast!
hello mr brandon wingert, you are my favorite teacher
I have to give props to another Austrian scientists: Sigmund Freud. He was also wrong about or oversimplified many of his hypothesis about the human psyche. It can be frustrating how people focus on his "failures" even though, like Mendel, he was the first to truly look into his field. I think it would be a good idea to look at his research and the birth of Psychology in SciShow. (I might be about to get my Psychology degree... maybe a bit biased. haha)
How about a video on Aristotle? I'll admit that he was wrong about most everything, but he ushered in an era of learning, was one of the first people to think logically and apply logic to everything, and he created what eventually would become modern science. He could also be considered the only person to heavily influence science and religion, without one of the two hating him.
Where were you when I needed to pass my Biology exam. It's been 2 years I left middle school and just now I understood what Mendel's Law really is.....
The white squirrel plus black squirrel makes grey squirrel thing isn't entirely false. It's called incomplete dominance and can occur in some flowers where breeding red and white ones can make pink.
It is more on the fundamental/biological side. I believe it has to do with when gametes are created through meiosis, a cell with the full 46 chromosomes splits into the two gametes, each gamete gets one of the alleles and the second one gets the other. So each sperm or egg is given one allele for every one of the parents trait, and the other goes to a sperm or egg cell that has the other one. Hope that helps
Yes Please!
@Visaals4 It's because the alleles for skin color have incomplete dominance over each other, which results in a phenotype that is a mixture of both alleles (for example, if the alleles for flower color between a red flower and a white flower have incomplete dominance, the offspring will be a pink flower)
Learning about Mendel was one of my favorites moments in school. He really was an amazing mind.
He died nearly seven years ago but what would be his 78th birthday happened last month. His 7th death anniversary would be on August 21st so maybe Hank could upload a video about him on that day as tribute.
Please make one about Nikola Tesla! More people need to know about his genius.
Also, thank you so much for this video (and all the others. We recently discovered this channel and Crash Course and vlogbrothers with my boyfriend and we just can`t stop watching. What you guys do is the epitome of awesome!)
I was wondering where the randomness originated, and it makes sense now. Thanks for answering my question.
Just watched this in school and didn’t notice this was the iconic Hank Green
