Question

Quizplus · Accepted Answer

Natural selection favors traits that provide a reproductive advantage in a specific environment, leading to the accumulation of advantageous genetic variations in a population. As a result, less advantageous alleles or variations tend to decrease in frequency or even disappear. This leads to a decrease in the amount of variation associated with that trait in the population over time.
