Question

8. (2 pts) Coat color in guinea pigs is controlled by a single pair of alleles. When 20 purebred white guinea pigs are bred with a black male guinea pig of unknown ancestry, 35 of the offspring are white in color and 42 are black in color. a. What is the likely genotype of the original black male guinea pig? b. Is the white color controlled by a dominant or recessive allele?

Step 1

We are given a genetic cross between 20 purebred white guinea pigs and a black male guinea pig of unknown genotype. The offspring consist of 35 white and 42 black guinea pigs. We need to determine the genotype of the black male guinea pig and whether the white Show more…
