Name and describe (in your own words) the four sources of variance which make up phenotypic variance. Four sentences. Clear, simple, and precise please.

Solution

These include genetic effects,parental effects just after conception,developmental effects due to interactions between genes and environment,and the biotic and abiotic environment effects through to the point at which the trait is expressed.Additive,dominance,and epistatic effects can all contribute to the phenotype of a quantitative trait,but generally additive interactions are the most important.The phenotype is a sum of the environmental and the genetic effects.
