Disruptive selection is a way of natural selection where extreme phenotype gets selected by the nature. Whenever there is sudden change in the environment, it creates sudden forces which favors the selection of extreme phenotype. In simple terms rather than having one ideal phenotype as observed in stabilized environment nature selects different types in the changing environment.
