Heterozygous Cc chickens express a condition called creeper, in which the leg and wing bones are shorter than normal so they appear to have a creeping gait. The c allele is lethal when homozygous and the CC genotype produces a normal gait. Two alleles of an independently segregating gene determine white ( W ) versus yellow ( ww ) feather color. From a cross between chickens heterozygous for both of these genes, which phenotypic classes will be represented among the progeny, and what are their expected relative frequencies? ( 2 pts)
