Round seeds R is dominant to wrinkled seeds r and yellow see

Round seeds (R) is dominant to wrinkled seeds (r), and yellow seeds (Y) is dominant to green seeds (y). A true-breeding pea plant with round and yellow seeds is crossed to a true-breeding plant with wrinkled and green seeds. The F_1 progeny are allowed to self-fertilize. What is the probability of obtaining a yellow seed in the F_2? 3/4 1/16 9/16 3/16

Solution

Answer :

P1= RRYY x rryy

F1 = RrYy

F2 =RrYy x RrYy

12 yellow seeds out of 16 = 3/4
