“Epistasis” is a word composed of Greek roots that mean “standing upon.” The alleles that are being masked or silenced are said to be hypostatic to the epistatic alleles that are doing the masking.

Epistasis is a circumstance where the expression of one gene is affected by the expression of one or more independently inherited genes. 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. In this example, gene #1 is said to be epistatic to gene

An interaction between nonallelic genes in which the genotype at one locus affects the expression of alleles at another locus. In Fisher's 1918 definition, epistasis refers to a deviation from additivity in the effect of alleles at different loci with respect to their contribution to a quantitative phenotype. This definition is not equivalent to Bateson's 1909 definition, as was pointed out in the initial review of Fisher's 1918 paper by R.C. Punnett (8). In modern usage, epistasis refers to any relationship of nonadditive interaction between two or more genes in their combined effects on a phenotype.

What does epistasis mean? Information and translations of epistasis in the most comprehensive dictionary definitions resource on … An epistasis group is a group of genes in the same pathway. Knocking out any combination of these genes will not result in a more severe phenotype than knocking out the most "sensitive" of these genes (the single mutant with the most severe phenotype). Share.

Epistasis, Genetic Epistasi Svensk definition. En form av genetisk interaktion där ett genuttryck hindrar eller döljer ett annat eller andra genuttryck. Gener vars uttryck hindrar eller döljer effekterna hos andra gener sägs vara epistatiska mot de berörda generna.

Its meaning in biology is not well-defined and often leads to confusions. epistasis in British English. (ɪˈpɪstəsɪs ) noun. 1. obsolete.

Genes whose phenotype are Expressed-epistatic altered or suppressed-hypostatic ‘For geneticists, epistasis is associated with the limits of the additive model of gene action.’ ‘These results suggest that future genetic models for the evolution of aging should incorporate the effects of epistasis.’ ‘Neither earlier study was able to demonstrate a significant effect of epistasis, either positive or negative.’ 2018-02-19 · Epistasis: Dominant epistasis, dominant inhibitory epistasis, duplicate dominant epistasis, duplicate recessive epistasis, polymeric gene interaction, and recessive epistasis are the six types of epistasis. Examples. Dominance: Mendelian inheritance of the flower color of the pea plant is an example of dominance.
