{c}
{synonym}
The local response approximation $\Delta\overline{\mathbf z}=\mathbf G\boldsymbol\beta$, where $\mathbf G$ is the <additive genetic covariance matrix> and $\boldsymbol\beta$ is a <phenotypic selection gradient>. Correlated inheritance can facilitate one direction of response and inhibit another.<Quantitative genetic analysis of multivariate evolution, applied to brain:body size allometry by Russell Lande>[Evolution 33, pp. 402–416]{ref}
