If natural selection favors an average phenotype by selecting against extreme variation, the population will undergo stabilizing selection. ... Stabilizing selection: Stabilizing selection occurs when the population stabilizes on a particular trait value and genetic diversity decreases.

What happens during stabilizing selection?

In summary, stabilizing selection happens when extreme phenotypes on both ends of the spectrum are unfavorable. This type of selection leads to enrichment of intermediate phenotypes and narrowing of the range of variation.

Which of these is an example of stabilizing selection?

Classic examples of traits that resulted from stabilizing selection include human birth weight, number of offspring, camouflage coat color, and cactus spine density.
