  1. Accuracies1 of QTL-EBV, polygenic EBV and total EBV for different values of heritability for marker-assisted BLUP with neighboring marker (NM), 2-marker haplotype (HAP2) and 4-marker haplotypes (HAP4) and conventional BLUP (CONBLUP) (sires and males in last generation are genotyped; distance between markers is 0.1 cM, the QTL explains 15% of the genetic variance, results are averages of 200 replicates)
  2. 1Standard errors were between 0.007 and 0.022 for QTL-EBV, between 0.002 and 0.006 for polygenic EBV and between 0.002 and 0.005 for total EBV
