disruptive selection

There are three types of selection:

Stabilizing selectionDirectional selectionDisruptive selection

1. Stabilizing selection

Selects for average individuals Decreases variation/diversity ⇒ the population has more of the average trait and less of the extreme traits

2. Directional selection

Selects for one of the extreme variations of a traitDecreases variation/diversity

3. Disruptive selection

Selects for both extremes of a trait's variationSelects against average phenotypesCan lead to speciation (formation of a new species)
