Heritability of traits is expressed as a mean and its standard error (SE), and the confidence interval (CI) expressed as of the 95% high posterior density interval of Gibbs sampling estimates (95% high posterior density interval of MCMC sampling estimates for the MCMCglmm software). All estimates were obtained by running single-trait analysis. Except for social dominance that has a direct, indirect and total heritability, the other traits only have a (direct) heritability
