Bias of genomic prediction of breeding value for carcass traits marbling score (MS), eye muscle area (EMA), carcass weight (CWT) and back fat thickness (BFT) comparing GBLUP, wGBLUP, and BayesR models using three SNP sets: (1) standard 50 k array (blue bars); (2) 50 k and eQTL-SNPs (green bars) and (3) 50 k and GWAS top-SNPs (grey bars). All analyses use cross-validation (CV) with 10,717 animals. Vertical lines indicate the empirical standard error for each CV result
