WebHowever, egg production is inherited as a polygenic trait, with low to moderate heritability (Luo et al., 2007; Biscarini et al., 2010; Venturini et al., 2013), making genetic improvement of this trait more costly based on estimated breeding values, but poorly effective by using traditional breeding method (Qin et al., 2015b). A 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 Mendelian inheritance.
