Phenotypic covariance

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). WebDec 1, 2004 · The vector phenotypic measurements for individual i can be written as the sum yi = μi + ai + ei + ϵi, 1 where μi is a mean vector (which includes the population mean and can also include effects of gender, locale, etc.), and ai is the additive genetic component (the breeding value).
