dEBV = deregressed estimated breeding values; h² = estimated heritability utilizing the threshold model; σ²_SNP = variance explained by SNPs; σ_e² = residual variance; h²_SNP = proportion of phenotypic variance explained by SNPs, values in brackets [] indicate the proportion related to additive genetic variance; 10% σ_a² = number of windows that capture 10% of the genetic variance
