Polygenic trait refers to a trait that is controlled by multiple non-allelic genes. These genes are called polygenes. They are a group of genes that, when turned on, are expressed as a unit. Each of them produces an effect that adds up to the trait. Nevertheless, the effect of an indi...

Definition.A trait resulting from an allele that is independently and equally expressed along with the other. Supplement. An example of codominant trait is blood type, i.e. a person of blood type AB has one allele for blood type A and another for blood type B. How Is height a polygenic ...
Because multiple genes control the trait, or character, that is being observed, it is common to see a range of differences in that trait. Eye color is an example of a trait controlled by polygenic inheritance; it is thought to be controlled by up to fifteen genes!

D Zabaneh1, G Breen1,2, PF O'Reilly1 and R Plomin1 A primary goal of polygenic scores, which aggregate the effects of thousands of trait-associated DNA variants discovered in genome-wide association studies (GWASs), is to estimate individual-specific genetic propensities and predict outcomes....
For example, patients with a family history of diabetes may have more frequent examinations for cardiovascular diseases. Genome-wide association studies Studies in which up to millions of mostly common single-nucleotide polymorphisms from across the genome are each tested for association with a trait....
Eye coloris an example of polygenic inheritance. This trait is thought to be influenced by up to 16 different genes. Eye color inheritance is complicated. It is determined by the amount of the brown color pigmentmelaninthat a person has in the front part of the iris. Black and dark brown...
