Lesson Summary. In summary, directional selection is a type of natural selection in which individuals with a trait at one end of a phenotypic spectrum are most fit. Disruptive selection is a type of natural selection in which individuals at either end of a phenotypic spectrum are most fit.Stabilizing selection is a type of selection in which individuals in the middle of a phenotypic spectrum are most fit.esson Summary. In summary, directional selection is a type of natural selection in which individuals with a trait at one end of a phenotypic spectrum are most fit. Disruptive selection is a type of natural selection in which individuals at either end of a phenotypic spectrum are most fit.

Natural selection is a process in which the population of organisms that have adapted to their environment increases more than the population of less well-adapted forms. This concept was first explained in Charles Darwin's theory of evolution.
