In peas, the round allele is dominant over the wrinkled allele. If a plant with round peas is crossed to a plant with wrinkled peas, all of the resulting plants have round peas. What is the most likely genotype of the parents in this cross? Group of answer choices Rr x RR RR x rr Rr x rr Rr x Rr

Respuesta :

Answer:

RR x rr / Rr x RR

Explanation:

For all of the first final generation to all produce round peas, it means the parents crossed were pure breeds of both dominant and recessive genotype or one of the the parents is an heterozygote and the other is a pure breed dominant. The resulting peas will have a phenotype which is the observed round shape but their genotype may be either the homozygous RR or the heterozygous Rr.
