8. In gerbils, the gene that specifies coat color is sex-linked and has multiple alleles, as follows: B-black, br - brown, by - yellow, and b - albino. The allele br is incompletely dominant over by, the combination br by giving tan color; otherwise, dominance is in the order given -- B, br, by, b. (For your information, gerbils are mammals.) www A black gerbil mated with a yellow gerbil gave one brown male and one black female offspring. a. What is the sex of the black parent? b. What is the genotype of the brown offspring? c. If the two offspring were to mate with each other, what is the probability that they will have a yellow offspring? d. If the two offspring were to mate with each other, what is the probability that the first three female offspring will be black? e. If the brown offspring were to mate with his mother, what is the probability that the first two offspring will be brown males?

In human beings, the gene for red-green colorblindness (r) is sex-linked and recessive to its allele for normal vision (R), while the gene for freckles (F) is autosomal and dominant over its allele for nonfreckled (f).

What is the probability that the couple's first child will be a non-freckled, normal visioned girl c. What is the probability that the first two children born to the couple will be freckled and colorblind girls? d.
