WebA phenotypic correlation is the correlation between records of two traits on the same animal and is usually estimated by the product- moment correlation statistic. Genetic correlations require a genetically informative sample. They can be estimated in breeding experiments on two traits of known heritability and selecting on one trait to measure the change in the other trait (allowing inferring the genetic correlation), family/adoption/twin studies (analyzed using SEMs or DeFries–Fulker extremes analysis), molecular estimation of relatedness such as GCTA, methods employing polygenic scores like HDL (High-Definition Likelihood), LD score regr… WebPhenotypic correlations are likely to be fair estimates of their genetic counterparts in many situations.

WebThe total phenotypic variance is thus partitioned : V P = V A + V D + V I + V E. The point of this is that we want to know the additive genetic component of the total phenotypic variance since this is what makes parent and offspring look alike and is what selection can act upon.
