Questions

Cоаt cоlоr in mice is controlled by the interаction of two genes: Gene #1: The blаck coat color allele (B) is dominant over the brown coat color allele (b). Gene #2: Expression of coat color allele (C) is dominant over masking of coat color allele (c). Genotypes CC and Cc enable the expression of coat color, and the genotype cc will mask the expression of coat color, resulting in a white mouse.  What is the expected phenotypic ratio (Black: Brown: White) that results from a cross between two black mice heterozygous for both genes?  Select the right answer and show your work on your scratch paper for full credit.
