●● In guinea pigs coat color is determined by a single gene with two
alleles. A guinea pig from a true-breeding black strain is mated with a
guinea pig from a true-breeding white strain. The F1 progeny are all
black. Two of the F1 progeny are mated with each other. What
proportion of the F2 progeny is expected to be white?
A. 1/4
B. 1/3
C. 1/2
D. 3/4
E. 7/8
Answer: A. 1/4

●● In guinea pigs coat color is determined by a single gene with two
alleles. Allele B is dominant and encodes a black coat. Allele b is
recessive and encodes a white coat. If you cross a black guinea pig with
a white one, what is the phenotype ratio in the F1 generation?
