Table 6 Reliability (R 2 , %) of genomic predictions based on the 54K SNPs (54K_real) excluding one chromosome or a random sample of 827 markers, averaged over 15 traits

From: Genomic relationships based on X chromosome markers and accuracy of genomic predictions with and without X chromosome markers
