Genetics epistasis
WebJun 9, 2014 · Epistasis occurs if the effect of one variant affecting a complex trait depends on the genotype of a second variant affecting the trait. For example, consider two loci (A, B), each with two alleles (A 1, A 2, B 1, B 2 ). Epistasis would occur, for example, if the A 2 A 2 B 2 B 2 genotype had a high disease risk, but the eight other possible two ... WebJul 27, 2015 · EPISTASIS has long been recognized as an important component in dissecting genetic pathways and understanding the evolution of complex genetic systems (Phillips 2008).It is hence a biologically influential component contributing to the genetic architecture of quantitative traits (Mackay 2014).The influence of epistasis on genome …
