In pea plants, the allele for round seeds is dominant to the allele for wrinkled seeds. If a plant that is heterozygous for seed type is crossed with one that has only homozygous wrinkled seeds, what percent of their offspring would you expect to have wrinkled seeds?

The answer is 50% 
A - allele for round seed
a - allele for wrinkled seed

The cross is:
Parents:     Aa    x    aa
Offspring: Aa  Aa  aa  aa

So, aa will have wrinkled seed, and there are 2 of 4 offspring with aa genotype. 2/4 = 0.50 = 50%

Explanation:

the correct answer is 50%
