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

From: Animal models with group-specific additive genetic variances: extending genetic group models

  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
