We review and discuss the importance of correlational selec-
tion (selection for optimal character combinations) in natural
populations. If two or more traits subject to multivariate
selection are heritable, correlational selection builds favour-
able genetic correlations through the formation of linkage
disequilibrium at underlying loci governing the traits. How-
ever, linkage disequilibria built up by correlational selection
are expected to decay rapidly (ie, within a few generations),
