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 [1]), a type of non-Mendelian inheritance, as opposed to single-gene inheritance, which is the core notion of ...

homeotic gene, any of a group of genes that control the pattern of body formation during early embryonic development of organisms. These genes encode proteins called transcription factors that direct cells to form various parts of the body.

The meaning of POLYGENE is any of a group of nonallelic genes that collectively control the inheritance of a quantitative character or modify the expression of a qualitative character.

Feb 13, 2017 · Polygenic inheritance, also known as quantitative inheritance, refers to a single inherited phenotypic trait that is controlled by two or more different genes.

Jul 31, 2023 · Polygenes refer to a group of multiple genes that contribute to the expression of a specific trait or characteristic. Unlike single genes that have a clear-cut influence, polygenes work together to influence a trait’s variation and complexity. Each individual gene has a small effect, but their cumulative impact is significant.

Jun 30, 2023 · Polygenic inheritance, in simple terms, implies a character or phenotypic trait, which is regulated by more than one gene. In biology, it refers to the quantitative inheritance wherein two or more independent genes additively affect a single phenotypic trait.

May 8, 2019 · When specific features of an organism are determined by many genes, the feature is a polygenic trait. Many of the observable characteristics of an organism are influenced by more than one gene, and the corresponding polygenic inheritance becomes complex.

Jan 1, 2022 · A polygene is any gene that interacts with one or more other genes to influence some aspect of phenotypic expression. Physical characteristics such as height, skin color, and eye color in humans are examples of polygenically controlled phenotypes.

Mar 27, 2019 · Polygenic traits are traits that are controlled by multiple genes instead of just one. The genes that control them may be located near each other or even on separate chromosomes. Because multiple genes are involved, polygenic traits …

“Polygene” is a term used for an etiologically relevant gene in a chromosomal locus that harbors intragenic or extragenic interindividual sequence variations accounting for a small fraction of the variation of a specific quantitative trait.
