Hill-Robertson Interference Reduces Genetic Diversity on a Young …

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.
