In cats, curled ears (Cu) results from an allele that is dominant over an allele for normal ears (cu). Black color results from an independently assorting allele (G) that is dominant over an allele for gray (g). A gray cat homozygous for curled ears is mated to a homozygous black cat with normal ears. All the F1 cats are black and have curly ears.

(a) If two of the F1 cats mate, what phenotypes and proportions are expected in the F2?

(b) An F1 cat mates with a stray cat that is gray and possesses normal ears. What phenotypes and proportions of progeny are expected from this cross?
