WebSep 27, 2024 · As genetic methods have become more sophisticated and less costly, genome-wide association studies (GWASs) have become more prevalent. GWASs are hypothesis-free analyses that assess associations between a phenotype of interest and a large number of common genetic variations (hundreds of thousands to millions of single … 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…
