Under purifying selection

In natural selection, negative selection or purifying selection is the selective removal of alleles that are deleterious. This can result in stabilising selection through the purging of deleterious genetic polymorphisms that arise through random mutations. 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 mut… Web1 Jun 2024 · It is tempting, particularly in a context of continuing ambiguity, to stipulate that maintenance under purifying selection for performance of some effect is all that …
