What are the components of natural selection

Polygenic traits in a population often form a bell curve distribution. Natural selection on polygenic traits can take the form of: Stabilizing selection: Intermediate phenotypes have the highest fitness, and the bell curve tends to narrow. Directional selection: One of the extreme phenotypes has the highest fitness.
