Question

The American Curl is a breed of cate that has curly ears. The allele for curly ears is dominant. Suppose a male cat with the heterozygous genotype is bred to a female cat with the homozygous recessive genotype. Predict the ratio of kittens that will have the phenotype for curly ears. In your answer:
a. Write the genotypes for both parents; draw a Punnet Square that shows a cross between the 2 cats

b. Write the phenotypic ratio of the offspring. If the cross produces six kittens, predict how many of them will have the curly ear phenotype

Answer 1

Cc * cc = Cc, Cc, cc, cc

Cc : 50%       cc: 50%

Three kittens will have the genotype for curly ears and three won't have the genotype for it.
