Other uses Negative selection disambiguation In natural selection , negative selection ref Loewe, L. 2008 . http www.nature.com scitable topicpage Negative Selection 1136 Negative selection . Nature Education 1 1 . ref or purifying selection is the selective removal of alleles that are Mutation Harmful mutations deleterious . This can result in stabilizing selection through the purging of deleterious variations that arise. Purging of deleterious alleles can be achieved on the population genetics level, with as little as a single point mutation being the unit of selection. In such a case, carriers of the harmful point mutation have fewer offspring each generation, reducing the frequency of the mutation in the gene pool. In the case of strong negative selection on a locus, the purging of deleterious variants will result in the occasional removal of genetic linkage linked variation, producing a decrease in the level of variation surrounding the locus under selection. The accidental purging of non deleterious alleles due to such spatial proximity to deleterious alleles is called background selection . ref Brian Charlesworth Charlesworth, B. , Morgan, M.
