Disruptive selection is the opposite of stabilizing selection
because the intermediate types are selected against.
In an experiment disruptive selection was applied to a population of Drosophila on the basis of bristle number.
In each generation, only the flies with high- or low-bristle numbers are allowed to breed.
After several generations, most of the flies could be easily placed in a low- or high-bristle category.
In natural populations, such a situation might exist for a population in a heterogeneous HinT
