Table 1 Estimates (posterior modes; posterior means) and 95% CI (defined as the 2.5 to 97.5% quantile intervals, given in parentheses) of the three group-specific additive genetic variances (\({\hat{\sigma }}_A^2\)) for inner, outer and other genetic groups, as well as for a single homogeneous variance across groups (total) for body mass and wing length

  1. The sample sizes denote the equivalent of full animal genomes that are present in the three genetic groups (\(n_j\), for the model with heterogeneous variances) or in the total dataset for the respective trait (n, for the homogeneous model). For comparison, the phenotypic variances (\({\hat{\sigma }}_P^2\)) of the total population and the three groups are given, where the group-specific versions were calculated only from the 992, 144 and 50 pure-bred animals in the inner, outer and other groups
