Epistasis is basically the influence of one gene with the expression of another gene. From the given example, The expression of the recessive e allele would mask the expression of color found in the B/b gene, and thus, would lead to three possible colors.
A black lab (BbEe) was mated to a chocolate lab (bbEe). What are the expected genotypic and phenotypic frequencies of the offspring? Provide percentages for your answers.
Remember epistatic effects: B_ = black; bb = chocolate; E_ = will have color; ee = yellow
