Polygenictrait
WebA single-gene trait is a trait that is controlled by only one gene. For instance, if long hair on guinea pigs was dominant, then short hair would be recessive; and the guinea pig would either just have long or short hair. The long hair on the black and white guinea pig would be dominant over the short hair. Someone can either have a widows peak ...

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). WebP. thornei resistance in chickpea is a polygenic trait (Channale et al., 2024) and genome-wide association study (GWAS) serves as an ideal method for genetic dissection of complex traits. GWAS takes advantage of evolutionary recombination events in crops to determine the molecular variations associated with the traits including disease responses ( …

Here we review the recent literature on models of polygenic adaptation. In particular, we focus on a model that includes mutation and both directional and stabilizing selection on a highly polygenic trait in a population of finite size …
WebDec 31, 2024 · Though classical Mendelian inheritance explains that a trait is controlled by a single gene, most human traits are polygenic traits which are controlled by more than one gene. Polygenic traits are complex and cannot be explained by Mendel’s pattern of inheritance. Human height is a polygenic trait. 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. The term "monozygous" is usually used to refer to a hypothetical gene as it is often difficult to distinguish the effect of an in…
WebSep 15, 2024 · A polygenic trait is a characteristic, such as height or skin color, that is influenced by two or more genes. Because multiple genes are involved, polygenic traits do not follow the patterns of Mendelian inheritance. Many polygenic traits are also influenced by the environment and are called multifactorial.
