  • The fraction of the replicated simulations, where the multimarker disequilibrium mapping estimate of the QTL position was in the correct bracket or in a bracket next to the correct bracket, and where the single-marker estimate was not more than two markers away from the QTL position, is shown. In the last generation a half-sib design was obtained by mating 10 randomly chosen males each to 10 females, yielding a total of 100 offspring. The effective size of the population and the number of generations since the mutation were each 100.
