WebThe phenotypic variation in populations is the result of genetic variation and two nongenetic sources of variation, namely, environmentally induced variation (EIV) and stochastic developmental variation (SDV). heat \u0026 air conditioning repair
Phenotypic Variability: Its Components, Measurement and …
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). VG = VA + VD + VI See more Genetic variance is a concept outlined by the English biologist and statistician Ronald Fisher in his fundamental theorem of natural selection. In his 1930 book The Genetical Theory of Natural Selection, Fisher postulates … See more Phenotypic variance, usually combines the genotype variance with the environmental variance. Genetic variance has three major components: the additive genetic variance, dominance variance, and epistatic variance. Additive genetic … See more 1.
