An excellent example of this is found in the genetics of the coat color of Labrador … Epistasis or modifier genes, that is, gene-gene interactions of non-allelic partners, play a major role in susceptibility to common human diseases.

This old genetic concept has experienced a major renaissance recently. Interestingly, epistatic genes can make the disease less severe, or make it more … An example of this type of epistasis is aleurone color in corn. The aleurone is the outer cell layer of the endosperm (food storage tissue) of the grain. In this system, a dominant gene (P_) 2021-04-08 · Epistasis, or interactions between genes, which grows at approximately the square of the number of genes (for example, >18 million interactions in the Saccharomyces cerevisiae genome). Epistasis is an interaction among loci such that the effect of a particular genotype at one locus on the expression of a trait is dependent on the genotype at other loci (Whitlock et al., 1995).

An excellent example of this is found in the genetics of the coat color of Labrador retrievers (Kaelin and Barsh, 2013; Figure 1). An example of epistasis is pigmentation in mice. The wild-type coat color, agouti ( AA ), is dominant to solid-colored fur ( aa ). However, a separate gene ( C ) is necessary for pigment production. examples from the literature are discussed.
