In a certain breed of chicken, an incompletely dominant gene controls color. The homozygous black,
when crossed with the homozygous splashed-white, produces an intermediate gray color pattern called blue. A second gene controls the shape of the comb. The dominant allele (R) produces rose, while the recessive allele (r) produces single. Give the F1 and F2 genotypic and phenotypic ratios of a cross between a pure-breeding, black single and a pure-breeding, splashed-white rose. What will be an ideal response?
