Table 1. Posterior statistics for fixed effects and random effects from a basic genetic groups animal model (GGAM) and an extended GGAM for dispersal probability in house sparrows. The GGAM had two genetic groups, corresponding to the farm and non-farm island habitats. The basic GGAM allowed mean breeding values for dispersal to differ between the two genetic groups, whereas the extended GGAM also allowed the additive genetic variances to differ between the two genetic groups. The mean posterior estimate with 95% credible interval (CI, in parenthesis) is presented for fixed effects. For random effects variances and proportions of phenotypic variance explained, the posterior mode and mean (formatted mode; mean) are presented, with the 95% CI in parenthesis. The proportion phenotypic variance explained by additive genetic variance is equal to the heritability of dispersal probability.
