A cross is made between pea plant having round and yellow seeds with pea plant having wrinkled and green seeds. What is the probability of obtaining yellow-colored seeds in the F2 generation?

a
34
b
14
c
12
d
1516

detailed solution

Correct option is A

When we cross pea plants having round and yellow seeds with pea plant having wrinkled and green seeds. The F2 generation has phenotypes in the ratio of 9 (Yellow and round):3(Yellow and wrinkled):3(green and round):1(green and wrinkled). Therefore, the probability of getting yellow seed is (9+3)/16= 12/16= ¾.
