In rabbits the dominant allele of a gene produces spotted body color, and the recessive allele solid body color. The dominant allele of another gene produces short hair, and the recesssive allele long hair.
True-breeding spotted short hair rabbits were bred with solid long hair rabbits. The resulting F1 generation consisted entirely of spotted short hair individuals. When the F1 rabbits were test-crossed with solid long hair rabbits. The results of the test-cross were as follows:
Spotted, short hair: 96
Solid, long hair: 80
Solid, short hair: 14
Spotted, long hair: 10
a. What is the expected phenotypic ratio for this cross?
b. Do these data support your hypothesis in part "a" above? (Make sure you mark down the genotypes of each of the groups before doing your chi-square analysis!)
c. Explain the observed results.
