The evolution of the G matrix: selection or drift?

Heredity - 1 Feb 2000

Roff D

Abstract excerpt

The evolution of quantitative characters can be described by the equation Deltaz=GP-1S where Deltaz is the vector of mean responses, G is the matrix of additive genetic variances and covariances, P is the matrix of phenotypic variances and covariances and S is the vector of selection differentials. This equation can be used to predict changes in trait values or to retrospectively estimate the selection gradient...
