Table 3 Sum of the phenotypic variances explained (PVE) by the peak SNP within each QTL region in the GWAS results of different reference populations (PB: purebreds in GP2; CB_extreme: two_tailed crossbreds in DLY; CB_random: random crossbreds in DLY) with different population sizes (500, 1000, 2000, 3000, 4000, 5000, 6000, 6500) for traits of different heritabilities (\({{h}}^{2}\)) (%)
