Reproductive characteristics of the flower breeding … 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 effect of the mutation is dependent on the genetic background in which it appears. … See more Understanding of epistasis has changed considerably through the history of genetics and so too has the use of the term. The term was first used by William Bateson and his collaborators Florence Durham See more Additivity This can be the case when multiple genes act in parallel to achieve the same effect. For example, when an organism is in need of See more Regression analysis Quantitative genetics focuses on genetic variance due to genetic interactions. Any two locus interactions at a particular gene frequency can be decomposed into eight independent genetic effects using a weighted regression. … See more Terminology about epistasis can vary between scientific fields.
