WebApr 3, 2024 · Modifying epistasis occurs when a gene at one locus modifies or changes the expression of the phenotype of a gene at the second locus. The gene that does the masking/modifying is referred to as epistatic, while the gene that is masked/modified is referred to as hypostatic. http://basicgenetics.ansci.cornell.edu/epistasis.php?section=mratios

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. ...
