B)3
C)4
D)5
E)9

Incomplete dominance means that neither allele is dominant over the other, and the heterozygote has a phenotype that is intermediate between the two homozygotes. In this case, the heterozygote will have a phenotype that is a blend of the two homozygotes. For example, if one homozygote has red radishes and the other homozygote has white radishes, the heterozygote will have pink radishes.When two dihybrid heterozygotes are crossed, the offspring will have a variety of phenotypes. The possible phenotypes are:- Red radishes- White radishes- Pink radishes- Purple radishes- Orange radishesThe number of different phenotypes is 5.
