Question

Quizplus · Accepted Answer

Stabilizing selection favors the average or norm of a population and selects against extremes. This occurs when individuals with intermediate phenotypes have a higher fitness than those with extreme phenotypes. As a result, the variation within the population decreases, while the mean stays relatively the same.
