In case of recessive epistasis
WebIn the case of single recessive epistasis the recessive allele of one gene in the homozygous state suppresses the expression of a dominant allele of another ( for example, "bb" suppress "A" ). For example, the color in rabbits is determined by two genes: "P" - presence of pigment, "p" - lack of pigment, and "B" - black color, "b" - blue color. ...
