WebThe variance of phenotypic values (VP) is an important measure in quantitative genetics. Just as the phenotype of an individual may be due to genetic and/or environmental influences, the variability within a population may be due to genetic or environmental differences among individuals. The phenotypic variance (VP) in a population is influenced by genetic variance (VG) and environmental sources (VE) VP = VG + VE The total amount of genetic variance can be divided into several groups, including additive variance (VA), dominance variance (VD), and epistatic variance (VI). green choice pool pump

Phenotypic variation (due to underlying heritable genetic variation) is a fundamental prerequisite for evolution by natural selection. It is the living organism as a whole that contributes (or not) to the next generation, so natural selection affects the genetic structure of a population indirectly via the contribution of phenotypes. Without phenotypic variation, there would be no evolution by natural selection.
