Determine the genotypes of the two parents

Reference no: EM1395128

A dominant allele, A, causes yellow color in rats. The dominant allele of another independent gene, R, produces black coat color. When the two dominants occur together (A/_ R/_), they interact to produce gray. Rats of the genotype a/a r/r are cream-colored. If a gray male and a yellow female, when mated, produce offspring approximately 3/8 of which are yellow, 3/8 gray, 1/8 cream, and 1/8 black, what are the genotypes of the two parents?
