In some mice, black fur (B) is dominant to white (b). At a different locus, a dominant allele (A) produces a band of red just below the tip of each hair. The expression of the recessive allele (a) results in solid coat color. If rabbits that are heterozygous at both loci are crossed:
-what proportion of their offspring is expected to have a solid color?
-what proportion of their offspring is expected to be white with a red band?
-what proportion of their offspring is expected to be black with a red band?
-what type of inheritance is this?
Homework Answers
Here the autosomal chromosomes are
responsible for the inheritance of the colour of the coat and sex
chromosomes are not involved, one dominant allele is enough to
express the trait in the individual and recessive allele is not
expressed. So, this type of inheritance is called autosomal
dominant.

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?

Fur color in dogs can be black, brown or white. The B gene is responsible for fur color. Dogs that inherit a dominant B will have black fur. Dogs that inherit 2 recessive alleles, bb, will have brown color. There is a second gene that contributes to fur color in dogs: gene I. Individuals who inherit a dominant allele, I, at this location, will always have white color. Individuals who inherit the homozygous recessive condition, ii, will be able to...

1) (4 pts) Black hair in rabbits is determined by a dominant allele, B, and white hair by homozygosity for a recessive allele, b.

1) Coat color in mice is determined by several independently assorting autosomal genes. Gene A is involved in the distribution of pigment along the hair. A dominant allele (A) produces a hair color called "agouti"--the hair has dark pigment at the base and tip of each hair shaft and yellow pigment in the central portion of the shaft. Homozygous recessive mice (aa) are missing the yellow stripe and thus have solid dark-colored hair. Gene B is involved in the color...

In the same mouse species, a fourth unlinked gene (gene P/p) also affects fur color.For mice that are either homozygous dominant (PP) or heterozygous (Pp), the organism’s fur color is dictated by the other three genes (A/a, B/b, and C/c).For mice that are homozygous recessive (pp), large patches of the organism’s fur are white. This condition is called piebaldism.In a cross between two mice that are heterozygous for agouti, black, color, and piebaldism, what is the probability that offspring will...
