  1. Bias1 (estimated - true breeding value) in QTL-EBV, polygenic EBV and total EBV for genotyped males and ungenotyped females 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 0.003 and 0.012 for h2 = 0.03, between 0.005 and 0.025 for h2 = 0.10 and between 0.009 and 0.037 for h2 = 0.30
