19.3B: Stabilizing, Directional, and Diversifying Selection

Natural selection is known to be one of the most important biological processes behind evolution. There are many variations of traits, and some cause greater or lesser reproductive success of the individual. The effect of selection is to promote certain alleles, traits, and individuals that have a higher chance to survive and reproduce in their specific environment. Since the environment has a carrying capacity, nature acts on this mode of selection on individuals to let only the most fit of… WebDiversifying selection refers to the situation in which natural selection favours different genotypes in different subenvironments.
