Epistasis - Definition, Types and Examples | Biology Dictionary
WebMar 27, 2019 · 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.
Epistasis - Wikipedia
WebEpistasis 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 effect of the mutation is dependent on the genetic background in which it appears.

WebApr 14, 2023 · Epistasis is a phenomenon in genetics whereby the presence or absence of mutations in one or more extra genes, referred to as modifier genes ( genetic modifiers ), affects the outcome of a gene mutation . In other words, the mutation’s fate is determined by the genetic environment in which it occurs.

WebFeb 28, 2021 · Epistasis is a form on non-Mendelian inheritance in which one gene is capable of interfering with expression of another. This is often found associated with gene pathways where the expression of one gene is directly dependent on the presence or absence of another gene product within the pathway.

WebThe term epistasis describes a certain relationship between genes, where an allele of one gene (e.g., ‘spread’) hides or masks the visible output, or phenotype, of another gene (e.g., pattern). Epistasis is entirely different from dominant and recessive, which are terms that apply to different alleles of the same gene (e.g., ‘bar’ is ...
