1. A couple of mice with brown fur and black eyes had litter with the following distribution of traits: 9 with brown fur and black eyes, 3 with brown fur and red eyes, 3 with grey fur and black eyes, and one with grey fur and red eyes. Propose an explanation.
Homework Answers
Given that brown fur and black eyes mice were mated and which results in the litter of new phenotypes such as grey furs and red eyes and the ratio of the litters is 9:3:3:1 ratio.
This result shows that the couple was heterozygous for brown fur and black eye alleles and brown fur is dominant over grey fur allele and the black eye is dominant over red eye allele.

In mice, black fur (B) is dominant to brown fur (b). At a different locus (C) allows the color deposition while (c) does not. Therefore, mice with cc genotype are albinos. If mice that are homozygous recessive for both characters are bred with mice who are heterozygous for both characters, what is the predicted phenotypic ratio of their offspring?

3) (2 pts) In a certain breed of dog, the dominant, B, is required for black fur; it's recessive, b, produces brown fur. However, the dominant, I, is epistatic to the color locus and can inhibit pigment formation to produce white fur. The recessive allele, i, on the other hand, permits pigment deposition in the fur.
