Question

In rats, gene B produces black coat color if the genotype is B

In rats, gene B produces black coat color if the genotype is B a??, but black pigment is not produced if the genotype is bb. At an independent locus, gene D produces yellow pigment if the genotype is D a, but no pigment is produced when the genotype is dd. Production of both pigments results in brown coat color. If neither pigment is produced, coat color is cream. A third independently assorting gene involved in determination of coat color in rats is the C gene. At this locus, the genotype C a?? permits expression of pigment from genes B and D. The cc genotype, however, prevents expression of coat color and results in albino rats. Determine the genotypes of parents that produce the following progeny: brown: yellow. Enter your answers separated by a comma. Express your answer using where any allele is possible. For example, for BbD _CC enter BbD_CC.
