Stabilizing selection

Explanation:

Stabilizing selection can be described as a kind of natural selection in which a specific trait remains constant over generations and it is shown more than the other traits. We can say that stabilizing selection favours those traits that are seen to be in majority in a population. It does not support the extreme phenotypes. The stabilizing trait can also be known as the average trait of that particular population.
