Solution

The correct option is A Round seeds
Round shape of seeds is dominant over the wrinkled shape of seeds in pea plants.

Let R and r be the alleles responsible for round and wrinkled seeds respectively.

When a plant homozygous for round seeds (RR) is crossed with a plant with wrinkled seeds (rr), the following results are obtained.


All the F1 offspring obtained are heterozygous for round seeds.
