Detailed explanation-1: -In natural and artificial selection, nature determines what traits will be passed down to offspring. AI Recommended Answer: In natural selection, traits benefit humans and in artificial selection, the traits benefit the species.

Detailed explanation-2: -Disruptive selection, also called diversifying selection, describes changes in population genetics in which extreme values for a trait are favored over intermediate values. In this case, the variance of the trait increases and the population is divided into two distinct groups.

Detailed explanation-3: -Stabilizing selection: Stabilizing selection occurs when the population stabilizes on a particular trait value and genetic diversity decreases.

Detailed explanation-4: -Stabilizing selection is very common. The individuals that survive and reproduce more successfully are those that have intermediate phenotypic values. Mortality among newborn infants, for example, is highest when they are either very small or very large; infants of intermediate size have a greater chance of surviving.
