The hitch-hiking effect. The hitch-hiking effect was presented as the variance of allele frequency changes at linked loci relative to the variance of allele frequency changes at unlinked neutral loci, as a function of distance from the QTL (in cM); allele frequency changes of all linked loci were calculated and sorted by their distance in cM to the closest QTL; subsequently we performed a sliding window of 40 000 records of variance of allele frequency changes at each linked locus; note that the scale of both axes differ for scenarios with different numbers of QTL.
