Polygene - Wikipedia
WEBA polygene is a member of a group of non-epistatic genes that interact additively to influence a phenotypic trait, thus contributing to multiple-gene inheritance (polygenic inheritance, multigenic inheritance, quantitative inheritance), a type of non-Mendelian inheritance, as opposed to single-gene inheritance, which is the core notion of ...

WEBFeb 27, 2021 · A polygene refers to a group of gene s that when expressed together produce a particular phenotype or trait. The trait produced is therefore a result of the expression of multiple genes. This type of trait is referred to as a polygenic trait. In humans, it is exemplified by skin colour, height, and weight.
