We investigated the correlated responses to clonal selection on body size in populations of the cyclic parthenogen Daphnia pulicaria that differ in frequency of sex. We found that most correlated responses to selection on body size were larger in populations with more frequent sex. This supports the hypothesis that selection for trait correlations combined with the power of recombination to create favorable genotypes is an important driver of genetic correlations.
