Table 3 Significance of fixed effects (assessed with type III anova) and random effects (assessed with loglikelihoods) across three sites (forking assessed at two sites only). Family (not shown) was highly significant (p < 0.0001) for all traits. Binary traits with zero variances are indicated in the table
