Estimated heritabilities (h²) (diagonal), phenotypic (r_P) (above diagonal) and genetic (r_G) (below diagonal) correlations for milk yield, and protein, fat, and dry matter contents (in kg) obtained in bivariate analyses through REML methods in goat milk including and excluding αS1-Casein genotype as a fixed effect.
