Epistasis and its implications for personal genetics. Moore JH(1), Williams SM. Author information: (1)Computational Genetics Laboratory, Department of Genetics and Department of Community and Family Medicine, Dartmouth Medical School, Lebanon, NH 03756, USA. 2008-03-14 · Quantitative genetics studies diverse populations and background variation is almost always present. 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.

For example, if the expression of gene #2 depends on the expression of gene #1, but gene #1 becomes inactive, then the expression of gene #2 will not occur.


We observed that among the main 15 complications for which these patients are at risk, only about five or fewer complications are apparent in each patient. One such type of complex inheritance is known as epistasis, in which the activity of a gene is influenced by one or more genes at separate loci to determine a single phenotype.

Epistasis genetics

In poultry white birds belong to two different varieties namely white leghorns or white Wyandotte’s. Epistasis in 2019-03-27 · 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.

Within quantitative genetics, the term “epistasis” is used to broadly describe situations in which combinations of genetic variants show nonadditive phenotypic effects (Phillips 1998, 2008; Mackay 2014). Epistasis Matters in Quantitative Genetics W ithinquantitativegenetics,theterm“epistasis”isused to broadly describe situations in which combinations of genetic variants show nonadditive phenotypic effects (Phillips 1998, 2008; Mackay 2014). Although most work on epistasis has focused on pairs of variants that interact Epistasis is an important concept in biochemical genetics, population genetics, and quantitative genetics.

In these qualitative trait models gene interactions typically result in masking or covering the effect of some What is epistasis? This video explains that it is a form of gene interaction. It presents both its molecular basis and its genetic manifestation. It explains In genetics, epistasis refers to the existence of some genetic interactions between some loci; in population genetics it refers more precisely to how such interactions affect phenotypes and fitness (W olf et al. 2000).
