In an example of recessive epistasis the deposition of pigment into hair follicles of the Labrador Retriever is governed by a dominant gene (C) and lack of deposition by its recessive allele (c). Lack of pigment deposition produces a yellow coat color. The color of pigment is governed by an independently assorting hypostatic gene, the dominant allele (B) produces black pigment and its recessive allele (b) produces brown. What coat color ratio is expected from the cross of a brown dog (bbCc) to a black dog (BbCc)? 3/8 black, 1/8 brown, 1/2 yellow 3/8 black, 3/8 brown, 1/4 yellow 1/2 brown, 1/2 black 1/2 black, 1/4 brown, 1/4 yellow 1/4 black, 1/4 brown, 1/2 yellow
