WebJul 17, 2024 · If natural selection favors an average phenotype, selecting against extreme variation, the population will undergo stabilizing selection (Figure 1a). In a population of mice that live in the woods, for example, natural selection is likely to favor individuals that best blend in with the forest floor and are less likely to be spotted by predators. WebDiversifying Selection. Sometimes two or more distinct phenotypes can each have their advantages and be selected for by natural selection, while the intermediate phenotypes are, on average, less fit. Known as diversifying selection , this is seen in many populations of animals that have multiple male forms. Large, dominant alpha males obtain ...
