Within the breed: heritabilities (on diagonal, in italic), genetic correlations estimated from bi-variate linear mixed model (lower diagonal) and genomic correlations estimated from signed t-values of all SNPs between traits (upper diagonal) which was matrix V in within-breed multi-trait meta-analysis
