  1. Regression1 of true on estimated breeding values for 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 0.015 and 0.060 for QTL_EBV, between 0.004 and 0.015 for polygenic EBV and between 0.004 and 0.014 for total EBV; regressions where the variance of the predicted nhc was smaller than 0.0001 were omitted (denominator of regression coefficient)
