Prediction of haplotypes for ungenotyped animals and its effect on marker-assisted breeding value estimation

Table 5 Accuracy of EBV for genotyped males and ungenotyped females in different genotyping scenarios

Accuracies¹ of QTL-EBV, polygenic EBV and total EBV for different genotyping scenarios for marker-assisted BLUP with neighboring marker (NM), 2-marker haplotype (HAP2) and 4-marker haplotypes (HAP4) (distance between markers is 0.1 cM, heritability is 0.30, the QTL explains 15% of the genetic variance, results are averages of 200 replicates)
¹Standard errors were between 0.005 and 0.021 for QTL_EBV, between 0.002 and 0.003 for polygenic and total EBV; ² in the first scenario sires from generation 101-104 and males in generation 105 were genotyped (1,200 genotyped animals); in scenario 2 all males were genotyped (5,000 genotyped animals) and in the last scenario all animals are genotyped (10,000 genotypes)
