Abstract The aim of this paper was to compare the effect of haplotype definition on the precision of QTL-mapping and on the accuracy of predicted genomic breeding values. In a multiple QTL model using identity-by-descent IBD probabilities between haplotypes various haplotype definitions were tested . including 2 6 12 or 20 marker alleles and clustering base haplotypes related with an IBD probability of or . Simulated data contained 1100 animals with .
