Detailed explanation-1: -Simply stated, there is no common cause of stabilizing selection, besides the fact that the most average individual is selected for. In that way, like all forms of selection, the cause of stabilizing selection is the increased fitness and reproductive success that the median individuals have.

Detailed explanation-2: -Stabilizing selection: Stabilizing selection occurs when the population stabilizes on a particular trait value and genetic diversity decreases.

Detailed explanation-3: -A few prominent examples of stabilizing selection are: Tree height. The prevalence of an intermediate fur color in mice. Beak size in a bird population.

Detailed explanation-4: -The most common form of stabilizing selection is based on phenotypes of a population. In phenotype based stabilizing selection, the mean value of a phenotype is selected for, resulting a decrease in the phenotypic variation found in a population.
