Arooster with e particular comb morphology called walnut was crossed to a hen with e type of comb morphology known as single. the fl progeny ell had walnut combs. when fl males and females were crossed to each other, 93 walnut end 11 single combs were seen among the f2 progeny, but there were also 29 birds with e new kind of comb called rose and 32 birds with another new comb type celled pee. a. explain how comb morphology is inherited. b. what progeny would result from crossing a homozygous rose-combed hen with e homozygous pea-combed rooster? what phenotypes and ratios would be seen in the f2 progeny? c. a particular walnut rooster was crossed to a pea hen, and the progeny consisted of 12 walnut, 11 pee, 3 rose, end 4 single chickens whet are the likely genotypes of the *rents? d. a different walnut rooster was crossed to a rose hen, and ell the progeny were walnut whet are the possible genotypes of the parents?
