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 ...

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.

2021年2月27日 · A polygene refers to a group of genes 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.

2017年4月28日 · Polygenic inheritance, also known as quantitative inheritance, refers to a single inherited phenotypic trait that is controlled by two or more different genes.

2022年1月1日 · 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.

tumour suppressor gene, any of a class of genes that are normally involved in regulating cell growth but that may become cancer -causing when damaged. Tumour suppressor genes encode for proteins that are involved in inhibiting the proliferation of cells, which is crucial to normal cell development and differentiation.

2019年3月27日 · 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 do not follow Mendel’s pattern of inheritance.

2019年5月8日 · 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.

2023年7月31日 · 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.

2023年6月30日 · 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.
