Mutational correlations for each pair of traits are above the diagonal; mutational variances are on the diagonal; mutational covariances are below the diagonal. *, **, and *** denote significant differences from zero at the 0.05, 0.01, and 0.001 levels, respectively. Italics indicate estimates that were nonsignificant after correction for multiple comparisons (sequential Bonferroni; Rice 1989).
