Question

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 $\left(\mathrm{B}^{\prime}ight)$ show incomplete dominance, so that $\mathrm{BB}^{\prime}$ individuals possess grey feathers. If chickens heterozygous for both pairs of genes are mated, what proportion of offspring are expected to be single combed and grey feathered?\
