  1. Negative selection (natural selection)

    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.

    Other uses Negative selection disambiguation Refimprove date July 2007 Merge Tall poppy syndrome date June 2010 Negative selection is a political process that occurs especially in rigid hierarchy hierarchies , most notably dictatorship s, but also to lesser degrees in such settings as corporations or electoral politics. The person on the top of the hierarchy, wishing to remain in power forever, chooses his associates with the prime criterion of incompetence &ndash they must not be competent enough to remove him from power. Since subordinates often mimic their leader, these associates do the same with those below them in the hierarchy, and the hierarchy is progressively filled with more and more incompetent people. If the dictator sees that he is threatened nonetheless, he will remove those that threaten him from their positions &ndash purge the hierarchy. Emptied positions in the hierarchy are normally filled with people from below &ndash those who were less competent than their previous masters. So, over the course of time, the hierarchy becomes less and less effective. Once the dictator dies &mdash or is removed by some external influence &mdash what remains is a grossly ineffective hierarchy.

    DISPLAYTITLE Natural Selection manuscript Natural Selection is a manuscript written by Charles Darwin , in which he presented his theory of natural selection and its role in biological evolution . He did not publish the work while he was alive, but wrote an abstract, titled On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life , which he published in 1859 . Darwin regarded Natural Selection as his main work, while On the Origin of Species was written for a wider audience. He always intended to finish Natural Selection , but because of frail health, the publicity and work involved in publishing six editions of On the Origin of Species , plus other research and publications, he never got around to finish it. Natural Selection was transcribed after Darwin s death, and first published in 1975.

This is probably the most common mechanism of action for natural selection. Stabilizing selection commonly uses negative selection a.k.a. purifying selection to select against extreme values of the character. Stabilizing Selection is the opposite of disruptive selection, instead of favoring individuals with extreme phenotypes, it favors the intermediate variants. It reduces phenotypic variation and maintains the status quo.
