Dihybrid cross. The kernels (seeds) on an ear of corn are all offspring of one set of parents. There are 2 pairs of alleles on separate homologous chromosomes (purple or yellow kernels on one pair, plump or shrunken kernels on another). Yellow (Y) is dominant to purple (y) and plump (P) is dominant to shrunken (p). If the genotype of parent plants are YyPp and yyPp, what are the expected probabilities of the genotypes and phenotypes of the offspring kernels? Explain your reasoning.
