The allele for pea comb (P) in chickens is completely dominant to the allele for single comb (p) . The alleles for black feather colour (B), and white feather colour (B') show codominance, so that BB' individuals possess blue feathers. If chickens heterozygous for both pairs of genes are mated what proportion of offspring are expected to be pea combed and white feathered ?
