Answer:

Option C is correct.

Explanation:

Given the genotype of two parents-

Parent pea Plant I - Rr

Parent pea Plant II - rr

When these two parents are crossed with each other the following offspring are produced -

R r

r Rr rr

R represents the round seed and it is a dominant trait.

r represents wrinkled seed and it is a recessive trait.

From the punnet square above, it is visible that out of four offspring 2 are recessive with genotype "rr"

hence, the probability that the offspring will have wrinkled seeds is

$\frac{2}{4} * 100\\= 50$ %

Option C is correct
