In Labradors, two genes interact to determine coat color. BB homozygotes and Bb heterozygotes are black, while bb homozygotes are brown. The second gene, E, is epistatic over the B gene, and ee homozygotes always have yellow fur. If you crossed a brown Labrador (bb Ee genotype) with a yellow Labrador (Bb ee genotype), what would be the expected phenotypic ratios of their progeny? Assume that the two genes are unlinked.
