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.
In a changing environment, natural selection will favor variations Variation: The differences among individuals in a population. that result in a better fitness in the new environment, resulting in adaptation and evolution. Directional selection Directional selection Directional Selection: A type of selection that removes individuals from one end of a phenotypic distribution and thus causes a shift in the distribution. occurs when natural selection favors one extreme of continuous variation. Over time, the favored extreme will become more common and the other extreme will be less common or lost.
