Definition noun Atraitproduced by the effect of ageneor an allele Supplement A monogenic trait is a trait produced by the effect of a gene or anallele. It is in contrast to a polygenic trait that is controlled by apolygene(multiple genes). Since the trait is produced by a single gene ...

Polygenic Trait Definition 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...
What is a pleiotropic trait? Pleiotropy (biology definition):the condition of having multiple effects. In genetics, it refers to a single gene controlling or influencing multiple (and possibly unrelated) phenotypic traits. Is hair color a polygenic trait? Human skin, hair, and eye color are also...

While this definition appears simple, it involves certain assumptions and nuances that are easy to miss or misinterpret. First, this definition does not naturally apply to binary traits. To define the heritability of a binary trait (e.g., schizophrenia), it is typically assumed that there ...

definition of the gene as the unvarying bearer of hereditary traits, its chemical identification by Avery (confirmed by Hershey), and the elucidation by Watson and Crick of the structural basis of its replicative invariance, are without any doubt the most important discoveries ever made in biology...
Definition noun (genetics) A genetic trait that results from the expression of the two recessive alleles. Supplement When the dominant allele is lacking or when the two alleles present are both recessive, their expression results in a recessive trait. Also called: recessive character Compare: ...
