1. RR x rr (Round x Wrinkled)Parent Genotypes:RR = Round (homozygous dominant)rr = Wrinkled (homozygous recessive)Punnett Square Result:All offspring = RrGenotype of offspring: 100% RrPhenotype of offspring: 100% Round(Because R is dominant over r)2. Rr x Rr (Wrinkled and Wrinkled)Assuming the question meant Rr x Rr (Round x Round):Punnett Square Result:25% RR50% Rr25% rrGenotypes: 1 RR : 2 Rr : 1 rrPhenotypes: 75% Round, 25% Wrinkled
