question 19 of 25
a population of mice lives in a city. the largest mice tend to be killed by predators, and the smallest mice cannot compete for food. what type of selection is this?
a. stabilizing selection
b. disruptive selection
c. directional selection
d. polygenic selection

Explanation:

Stabilizing selection favors intermediate phenotypes. Here, the largest (killed by predators) and smallest (can't compete for food) mice are selected against, leaving intermediate - sized mice favored. Disruptive selection favors extreme phenotypes. Directional selection shifts the population towards one extreme. Polygenic selection is not a standard type of natural selection term in this context.

Answer:

A. Stabilizing selection
