The effect of selection on the phenotypic variance

E E Shnol et al. Genetics. 1993 Jul.

Abstract

We consider the within-generation changes of phenotypic variance caused by selection w(x) which acts on a quantitative trait x. If before selection the trait has Gaussian distribution, its variance decreases if the second derivative of the logarithm of w(x) is negative for all x, while if it is positive for all x, the variance increases.
