When recessive alleles at one locus mask the expression of both (dominant and recessive) alleles at another locus, it is known as recessive epistasis. This type of gene interaction is also known as supplementary epistasis. A good example of such gene interaction is found for grain colour in maize.

This dependency of the effects of mutations on the genetic background in which they occur is known as epistasis or genetic interaction. The concept of epistasis

The implication of this is that epistasis may be detected in one experiment but not in another. This has led to criticisms that epistasis in the quantitative genetic sense is a statistical construct rather than a true representation of biology. The key difference between complementation and epistasis is that complementation is a genetic interaction in which a pair of genes often work together to create a specific phenotype, while epistasis is a genetic interaction in which one gene’s allele masks the phenotype of the other gene’s alleles.

The most well understood genetic models for gene interactions are described in terms of qualitative (Mendelian) rather than quantitative traits [37]. In these qualitative trait models gene interactions typically result in masking or covering the effect of some What is epistasis?

Epistasis Definition Epistasis is the interaction between genes that influences a phenotype. Genes can either mask each other so that one is considered “dominant” or they can combine to produce a new trait. It is the conditional relationship between two genes that can determine a single phenotype of some traits.

The wild-type coat color, agouti ( AA) is dominant to solid-colored fur (aa).

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 severe.

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 severe. Epistasis has been used to describe a number of phenomena, including the functional interaction between genes, the genetic outcome of mutations acting within the same genetic pathway, and the Epistasis is an important concept in biochemical genetics, population genetics, and quantitative genetics. Although its definition varies somewhat across these fields, the underlying concept is that the effects of allelic substitution at one gene can be dependent on the allelic state of another gene or genes. Epistasis is an interaction at the phenotypic level of organization.
