A) Directional selection. Chance events . Stabilizing selection . Disruptive selection. Answer Key – LO 1.2. Directional selection is most common wen a population’s environment changes or when members of a population migrate to a new habitat with different environmental conditions than their former one. Stabilizing selection acts against extreme phenotypes and favors intermediates variants. Disruptive selection occurs when environmental conditions favor individuals on both extremes of a phenotypic range over intermediate phenotypes. An example of directional selection is that black bears in Europe increase with size during the colder weather, only to decrease during the warmer weather. An example of stabilizing selection is the birth weights of most human babies lie in the range of 3-4 kg; babies who are much smaller or larger suffer higher rates of mortality. An example of disruptive selections is black- bellied seed cracker finches have two different beak sizes for cracking different types of seeds. .
