In cats, curled ears result from an allele, Cu, that is dominant over an allele cu, for normal ears. 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 F1 cats are black and have curled ears. What phenotypes and proportions are expected from teh following two crosses?1 - Two of the F1 cats mate?2 - An F1 cat mates with a stray cat that is gray and possesses normal ears. a. 1/4 black cats, curled ears; 1/4 black cats, normal ears; 1/4 gray cats, curled ears; and 1/4 gray cats normal earsb. 9/16 gray cats, normal ears; 3/16 gray cats, curled ears; 3/16 black cats, normal ears; and 1/16 black cats, curled earsc. 9/16 black cats, curled ears; 3/16 black cats, normal ears; 3/16 gray cats, curled ears; and 1/16 gray cats, normal earsd. All gray cats, normal earse. All black cats, curled ears.

Use this new information to determine the parents’ genotypes (indicated by red arrows). then calculate the probabilities that the second male offspring will have each condition. drag one pink label to each pink target and one blue label to each blue target. then use the white labels to answer questions 1 and 2. labels can be used once, more than once, or not at all.
