A pleiotropic model of phenotypic evolution.

Abstract excerpt

A pleiotropic model is presented for deriving the equilibrium genetic variance by mutation and stabilizing selection and the long-term genetic responses to directional selection in the case where mutations have pleiotropic effects on fitness itself (direct deleterious effect) and on a quantitative trait (phenotypic effect). The equilibrium genetic variance is derived as a general form of the rare-alleles models,...
