Question

question 25 of 25 a population of mice lives near a stream. the larger mice tend to live longer, and over many generations the average mouse size gets larger. what type of selection is this? a. directional selection b. stabilizing selection c. polygenic selection d. disruptive selection

Explanation:

Directional selection favors individuals at one extreme of a trait. Here, larger - sized mice are favored as they live longer and the average mouse size increases over generations. Stabilizing selection favors the average trait value, polygenic selection refers to selection on traits controlled by multiple genes (but doesn't describe the direction), and disruptive selection favors both extremes and not the average or one extreme.

Answer:

A. Directional selection
