How Mendel's pea plants helped us understand genetics - Hortensia Jiménez Díaz

Each father and mother pass down traits to their children, who inherit combinations of their dominant or recessive alleles. But how do we know so much about genetics today? Hortensia Jiménez Díaz explains how studying pea plants revealed why you may have blue eyes.

btw - If your teacher is having you do any dyhybrid crosses (2 or even more traits) you do not have to make some ridiculously massive, and likely error-ridden, punnett square. Simply take each trait and do a monohybrid cross. Then take that fraction and multiply it with the other trait's monohybrid cross. Example: Let's say the chance to get yy for a genotype was 1/4 in your 1st square, and then your chance to get Rr was 2/4 (note not to reduce) in the 2nd square, then your chance to get yyRr = 1/4 * 2/4 = 2/16

This works for phenotypes to, just be careful to add the fractions before multiplying when appropriate... like this:
RR = Round
Rr = Round
rr = wrinkled

If we had Genotype probability of RR = 1/4, Rr = 2/4, and rr = 1/4 then remember we have the PHenotype probability of

3/4 = Round... because the 1/4 from RR + 2/4 from Rr = 3/4;

while wrinkled is still just 1/4 from the rr

Wow!! If everything was explained like this with cute graphics everything would be so much easier! Thank you so much!

forget genetics, I love the way peas dance...

I messed about for a large portion of school but I’ve been revising over and over again and videos like this are really going to help me accomplish the large task of becoming a general practitioner

Lets be honest....






All of our teachers made us watch this

Bruh my teacher asked “Why did Mendel use peas for his experiment?”
The answer was “because they have 7 different traits and thus more variations”

I answered “Because they are cheap” 😭😭😭

peas are having an affair "you cheated on meee"

[giop]

Who is here only to see if someone has the answers that your teacher asked you in online classes?

[kaitlynheckman]

anybody else here bc the world decided it CORONA TIME

[Mercurzzzz]

That is so crazy, who knew that peas were so interesting? I'm addicted to watching kids science videos.

8 year old me looking at 0.16: I knew babies were made by kissing

Gregor Mendel. One of the forgotten geniuses of mankind just rediscovered later on.
His discoveries changed the world. He managed to figure out genetics long before someone understood what it actually was.

i am going to do the pea dance infront of my teacher after i pass my Bio exam ...hahaahahahah..jkjk
EDIT: (July 2020) lol it's been four years and i would like to say...i have passed that exam🤣 (in fact i am now in a medical college) *pea dancing *

Animator was definitely having the day of his life! Keep up the great work!

[mirabshabbir]

Love the way you explained this! So informative yet so entertaining!

Q: Why did Mendel always oppose war?
A: He thought we should give peas a chance.

Gregor Mendel was a hero. A genius. He was the father of genetics. We are standing on the shoulders of giants.

Yay I can pass my bio quiz tomorrow now, thanks!

Much easier to understand than 20 pages of a textbook with big words. thank you!
