In Mendel’s experiments, peas had two shapes: round and wrinkled. The round shape was dominant to the wrinkled shape. There are two alleles controlling this trait: R and r. The R allele is dominant to the r allele. A heterozygous plant with round seeds is crossed to a homozygous plant (i.e. it has two of the same alleles) with wrinkled seeds. What percent of the offspring from this test cross do you expect to have wrinkled seeds?
