Coat color in mice is controlled by the interaction of two genes: Gene #1: The black 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.

In gerbils, coat color is controlled by the agouti gene, in which the agouti allele (A) is dominant to the black allele (a). Additionally, coat pattern is controlled by the piebald gene, where the solid allele (S) is dominant to the piebald allele (s). Both genes are located on separate chromosomes. Consider a dihybrid cross between two solid agouti gerbils (AaSs x AaSs). Sort the gerbil phenotypes according to the 9:3:3:1 ratio one would expect to see in the F1 generation.
