Predictive correlations and prediction mean-squared error (MSE) for the six classes of genomic regions for body weight (BW), ultra-sound of breast muscle (BM) and hen house egg production (HHP) from the joint analysis of all additive kernels \(({\mathbf{G}}_{1} + {\mathbf{G}}_{2} + \cdots + {\mathbf{G}}_{6} ).\) The results were based on a fourfold cross-validation with 15 replications. “up-down” indicates regions that are located 5 kb upstream and downstream of the gene. “All” means that all SNPs were used to construct G. The whiskers represent 95 % confidence intervals
