WebExperiments on phenotypic variation Definition. The phenotypic variance of the trait is supposed to be caused by the additive effects of the segregating alleles in a population. These traits are not strongly genetically correlated with other traits that are also under selection. The phenotypic variance is referred to as phenotypic plasticity. WebMar 27, 2024 · The degree to which a given genetic variant has consequences for a particular person's phenotype reflects the qualities of penetrance and expressivity.
