Disruptive selection is an evolutionary force that drives a population apart. The Examples of Disruptive Selection. Darwin’s finches, or Galapagos finches, are a group of finches that inhabit the long Quiz. A population of deer has legs of The disruptive selection definition is defined as an evolutionary force that drives a population apart. The disruptive selection causes the organisms with intermediate traits in order to reproduce less, and allow those organisms with extreme traits to produce more. This fact causes the alleles for the extreme traits to increase the frequency.

This type of selection is not as common. When looking at a trait distribution, there are two higher peaks on both ends with a minimum in the middle as such:
disruptive selection A selection that changes the frequency of alleles in a divergent manner, leading to the fixation of alternative alleles in members of the population. The result after several generations of selection should be two divergent phenotypic extremes within the population. A population experiences disruptive selection when more extreme phenotypes (or genotypes) within a population have a fitness advantage relative to intermediate forms. Disruptive selection has garnered much attention among evolutionary biologists and ecologists because of its role in the evolution and maintenance of phenotypic (and genetic) variation and speciation, particularly sympatric speciation.

Disruptive selection can be a precursor to speciation. Disruptive selection favors both extreme phenotypes, different from one extreme in directional selection. Stabilizing selection is the opposite of disruptive selection.

Disruptive selection synonyms, Disruptive selection pronunciation, Disruptive selection translation, English dictionary definition of 1 Mar 2021 Disruptive Selection. Sometimes called Diversifying selection. This type of selection favors both the extremes at the expense of the average.
The disruptive selection will cause organsisms with intermediate traits to reproduce less, and will allow those organisms with extreme traits to reproduce more. 2013-06-14 2012-08-02 Disruptive Selection: Disruptive selection occurs when natural selection operates to favor two distinct phenotypes or behaviors which promotes diverging phenotypes rather than promoting a single Selection through lifetime female fitness acuminatus probably experience disruptive selection on male horns (Emlen 1994b; Emlen, unpubl. Artificial selection on horn length-body size allometry in the horned beetle Onthopagus acuminatus (Coleoptera: Scarabaeidae) 1983-05-01 Disruptive selection would act against the individuals with intermediate colours (grey or beige individuals), reducing the frequency of alleles that code for these colours. Disruptive selection can result in two distinct groups and if they become adapted to a different way of life (niche) they could eventually evolve into separate species (speciations). 2015-01-21 Directional selection will typically be followed by stabilising selection once an optimal phenotype has been normalised; An example of directional selection is the development of antibiotic resistance in bacterial populations; Disruptive Selection. Where both phenotypic extremes are favoured at the expense of the intermediate phenotypic ranges speciation via disruptive selection is the development of a nonrandom association (linkage disequilibrium) between two types of genetic variability: one for the disruptively selected trait, and another for positive assortative mating. Disruptive selection indirectly favors positive assortative mating and acts to build the requi- In disruptive selection the two extreme phenotypes are both favored over the average.
