Question

human babies are typically born within a very narrow range of weight. babies that are too heavy or too light are less likely to survive. in terms of natural selection, this is an example of

a stabilizing selection

b disruptive selection

c directional selection

d artificial selection

Explanation:

Stabilizing selection favors the average or intermediate phenotypes. In the case of human - baby birth weight, babies within a narrow weight range have a higher survival rate, while extreme (too heavy or too light) phenotypes are selected against, which is characteristic of stabilizing selection. Disruptive selection favors extreme phenotypes, directional selection shifts the population towards one extreme, and artificial selection is driven by human - made choices, not natural factors in this context.

Answer:

A. stabilizing selection
