Question: 2 in cats curled ears cu result from an allele...

Question details

2. In cats, curled ears (Cu) result 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 with a homozygous black cat with normal ears. All the Fi cats are black and have curled ears (a) If two of the Fi cats mate, what phenotypes and proportions are expected in the F2? (b) An Fi cat mates with a stray cat that is gray and possesses normal ears. What phenotvpes and proportions of progeny are expected from this cross?
