Hill-Robertson effect
From Wikipedia, the free encyclopedia
Hill and Robertson (1966) described an evolutionary advantage to genetic recombination.
In a finite population subject to natural selection and genetic recombination, genetic drift will create random instances of linkage disequilibrium. Some will be selectively advantageous, others will not. However, the creation of these slows down the progress of selection. Recombination breaks down the disequilibria, allowing selection to act independently on various loci.
