The American curl is a type of cat with curled ears. A single gene with two alleles codes for the ear-shape trait. The dominant allele (R) codes for curled ears, and the recessive allele (r) codes for straight ears. A heterozygous male curl cat is crossed with a heterozygous female curl cat.

a. Using the allele symbols above, identify the genotype of the parent cats.

b. Determine the expected phenotype ratio of the offspring that result from the cross. Draw a Punnett square to support your answer.

c. Which of Mendel's laws, the law of segregation or the law of independent assortment, is demonstrated by the cross represented by the Punnett square you drew in part (b)? Explain your answer.

d. Do the four squares in the Punnett square represent gametes or body cells? Explain your answer.
