ANOVA test statistics based on generalized mixed models, family “quasipossion”, with origin (origin of wasps from the same strain, from different strains but the same microsatellite cluster with k = 3 or k = 5 subpopulations, or the same microhabitat), female strain (strains from bird nests: N2, N3, N9; strains from carrion: A1, A7, A19), and female habitat (bird nest or carrion) as factors
