Polygenic inheritance definition, the heredity of complex characters that are determined by a large number of genes, each one usually having a relatively small effect. See more.

polygenic inheritance: inheritance in which a measurable phenotype is generated by many loci, the contributions of which are statistically independent, additive, and of about equal value. (The latter are in accordance with the classic central limit therein and justify the use of the multivariate normal distribution in galtonian genetics.) ...

Polygenic Inheritance Definition. Polygenic inheritance, also known as quantitative inheritance, refers to a single inherited phenotypic trait that is controlled by two or more different genes.. In a system which differs from Mendelian Genetics, where monogenic traits are determined by the different alleles of a single gene, polygenetic traits may display a range of possible phenotypes ...

Many of the inheritance patterns seen in nature are polygenic. Polygenic inheritance is when traits are influenced by more than one gene , which is a segment of DNA that codes for specific traits .

en.wikipedia.org/wiki/Polygenic_inheritance

Polygenic inheritance can be explained as Mendelian inheritance at many loci, resulting in a trait which is normally-distributed. If n is the number of involved loci, then the coefficients of the binomial expansion of ( a + b ) 2n will give the frequency of distribution of all n allele combinations .

polygenic inheritance (multifactorial inheritance; quantitative inheritance) The determination of a particular characteristic, e.g. height or skin colour, by many genes (polygenes), each having a small effect individually.

The definition of polygenic inheritance is.....a single characteristic that is controlled by two or more genes. Polygenic inheritance contributes to human skin color by.....increasing the number of genes (there can be as many as 4). When this happens, the phenotypic variation increases. The alleles in this control the pigment that controls the ...

Examples of polygenic inheritance in humans include height, eye color and skin color. Physical traits that have polygenic inheritance are influenced by more than one gene and typically display a continuous distribution, such as a range of heights. Polygenic traits do not have the classic phenotypic ratios of Mendalian inheritance.
