Explanation:

Stabilizing selection is the type of natural selection that select a non-extreme dominant trait. This trait is commonly present in a generation and it is stable for upcoming generations. No change in these traits occur over time except mutations in the genes. Stabilizing selection does not favor extreme phenotypes and it prefers intermediate phenotypical traits.
