  • The mean absolute difference of the QTL position estimate from its true position for the IBD mapping method used in populations created under the default scenario is shown. The QTL is located in the center of the 10-marker haplotype. The percentage of position estimates at or flanking the true QTL position is given for each haplotype size except for one marker. For a given marker spacing, least-squares means with different superscripts (a, b, c, d) are significantly different (P < 0.05).
