WebThe key distinction between stabilizing and disruptive selection is whether the relationship between fitness and a phenotype is concave down or up, respectively. Stabilizing selection, which is commonly invoked in theoretical studies of quantitative traits ( 5 – 9 ), will tend to reduce phenotypic variation while disruptive selection will ... WebDiversifying or disruptive selection increases genetic variance when natural selection selects for two or more extreme phenotypes that each have specific advantages. In diversifying or disruptive selection, average or intermediate phenotypes are often less fit than either extreme phenotype and are unlikely to feature prominently in a population.

WebDisruptive Selection: The natural selection that favors individuals with severe or unique features over those with typical or intermediate traits is known as disruptive selection. Divergent evolution, which can result from this, is the division of a single population into two or more distinct groups with various features. Answer and Explanation: 1 WebNov 26, 2024 · The disruptive selection theory of the evolution of anisogamy posits that the evolution of a larger body or greater organismal complexity selects for a larger zygote, which in turn selects for larger gametes. This may provide the opportunity for one mating type to produce more numerous, small gametes, forcing the other mating type to produce ...
