Polygene - Wikipedia 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
Polygenic Trait - National Human Genome Research Institute 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
POLYGENIC Definition Meaning - Merriam-Webster The meaning of POLYGENIC is of, relating to, mediated by, or constituting polygenes : involving two or more nonallelic genes collectively in determining inherited characteristics : multifactorial How to use polygenic in a sentence
Polygenic Inheritance: Definition, Characteristics, Examples Polygenic inheritance is defined as some phenotypic character determined by the additive effect of more than one gene on a single character Polygenic inheritance is commonly known as quantitative inheritance and multiple gene inheritance
Polygenic Traits: Definition, Example Facts - Sciencing 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
The Polygenic Model: How Genes Influence Complex Traits The polygenic model describes how multiple genes collectively influence a single trait, such as height, skin color, and intelligence This model is fundamental to understanding the genetic basis of many health conditions, including heart disease, diabetes, and certain psychiatric disorders
Polygenic Inheritance and Traits - ThoughtCo Polygenic inheritance describes the inheritance of traits that are determined by more than one gene These genes, called polygenes, produce specific traits when they are expressed together Polygenic inheritance differs from Mendelian inheritance patterns, where traits are determined by a single gene
Monogenic, Oligogenic, and Polygenic. . . whats the difference? As opposed to the other types of inheritance, the term polygenic refers to any trait that involves or requires complex interactions between multiple genes, variants, and additional non-genetic factors to be expressed
Polygenic trait Definition and Examples - Biology Online A polygenic trait is a trait that results from the expressions of many genes These genes apparently produced an additive effect on the phenotype of the offspring Thinks of it as a painting on an art canvas created by putting together different colors and intensities
