  1. Variance components for VAnimal, VPopulation, VUnit (representing residual variation including environmental effects) and resulting heritability (h2) as well as genetic correlations across environments (rG) with 95% confidence intervals. Estimates are based on standardized values. *fixed residual variation because categorical traits were used and heritabilities were not estimable.
