WebVariability refers to the potential of an organism or genotype to vary phenotypically, phenotypic differences we could observe across clones of the same genotype (i.e., red fly = high variability genotype, blue fly = low variability genotype). Variation refers to the realized (observable) differences between individuals or genotypes. Web7. jan 2024 · The additive genetic variance is The proportion of phenotypic variance is the narrow sense heritability h2 = VA/VP . These quantities are both measurements of the contribution of the current standing genetic variation in a particular set of environments and should not be thought of as fixed quantities of the population or trait.
