WebSep 18, 2024 · Epistatic interactions are the interactions between two or more genes that affect the phenotype of the trait they influence. There are several different types of … Originally, the term epistasis specifically meant that the effect of a gene variant is masked by that of a different gene. [3] The concept of epistasis originated in genetics in 1907 [4] but is now used in biochemistry, computational biology and evolutionary biology. See more Epistasis is a phenomenon in genetics in which the effect of a gene mutation is dependent on the presence or absence of mutations in one or more other genes, respectively termed modifier genes. In other words, the … See more Terminology about epistasis can vary between scientific fields. Geneticists often refer to wild type and mutant alleles where the mutation is implicitly deleterious and may talk in terms of genetic enhancement, synthetic lethality and genetic suppressors. Conversely, a See more Fitness landscapes and evolvability In evolutionary genetics, the sign of epistasis is usually more significant than the magnitude of epistasis.
