The type of selection that removes the fringe from both ends of phenotype distribution and establishing a means or average. Genetic diversity decreases and there is a stabilization on a particular trait.
A common cause of stabilizing selection Heterozygotes are fittest.
When natural selection favors the intermediate version of a characteristic, it is referred to as stabilizing selection. It is the opposite of disruptive selection.
Stabilizing selection
The three patterns of natural selection are directional selection, stabilizing selection, and disruptive selection. Directional selection favors individuals at one extreme of a trait distribution, stabilizing selection favors the intermediate phenotype, and disruptive selection favors individuals at both extremes of a trait distribution.
That would be the Stabilizing Selection where there will me not a lot of genetic variation. The curve of the population allele frequency would be quite thin with the extreme being in the middle.
disruptive selection
Directional selection
Industrial melanism is an example of directional selection, not stabilizing selection. In this phenomenon, environmental changes such as pollution cause a shift in the frequency of dark-colored individuals within a population, which increases their survival rates due to camouflage. Stabilizing selection, on the other hand, favors the intermediate phenotype, reducing the variation in a population.
