WebApr 1, 2010 · Figure 2 shows that a recombination modifier can be strongly selected for if introduced at 50% frequency; however, due to the high levels of Hill–Robertson interference present , it has a fixation rate that is only slightly higher than that of a neutral mutant (u/u* = 1.32). This suggests that measuring the strength of selection acting on a ... WebUnder Hill–Robertson interference (discussed above), genetic linkage is seen to increase the amount of genetic drift near a selected locus, thus reducing the effective population size for the locus when either a beneficial mutation arises or in the presence of purifying selection against a deleterious allele.
