Explain why wouldn't it be possible for two wrinkled pea plants to produce a smooth pea plant?

Question

Two Pea plants can produce wrinkled pea plants if they have the genotype Ss( one dominant and one recessive)

Answer 1

Wrinkled is recessive and round is dominant. The wrinkled peas do not have an allele for roundness, or they would be round. They are homozygous recessive.
