Estimated additive genetic (G) covariances and correlations (with SE) between two behaviours (aggression and exploration), and IGEs on aggression. We present covariances (lower-off diagonals) and correlations (upper-off diagonals) for each set of traits. Correlations printed in bold-face are significant (P < 0.05) based on likelihood ratio tests derived from the multivariate model detailed in the main text.
