Answer: B. The F1 generation carried recessive alleles.
Explanation: Recessive alleles are able to express only when these alleles are present in homozygous state. This means that only two recessive alleles together can show the respective phenotype. In F1 generation, since the genotype was heterozygous, for eg Rr, it was expressing the dominant trait only, i.e. round seeds. But after selfing of Rr and Rr in F2 generation, rr was formed. That is why, F2 contained wrinkled seeds.
Answer: the other apex answer is " wrinkled seeds are recessive"
