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

View full lesson: ed.ted.com/less...
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.
Lesson by Hortensia Jiménez Díaz, animation by Cinematic Sweden.

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

Interesting fact: You know Gregor Mendel formulated the laws of inheritance namely law of dominance, segregation, and independent assortment and Charles Darwin studied the evolutionary patterns in species by natural selection aka 'survival of the fittest' but Darwin could not work out the mechanism....it is ironic that he could have done so if he could have seen the significance of the experiments of the Austrian contemporary Mendel...but then too mendel did not notice his!!
