What is the difference between directional disruptive and stabilizing selection quizlet?

2:Disruptive Selection occurs when selection favors the extreme trait values over the intermediate trait values. 3:Stabilizing Selection occurs when selection favors the intermediate trait value over the extreme values.

What is the difference between disruptive selection and directional selection?

In directional selection, a population’s genetic variance shifts toward a new phenotype when exposed to environmental changes. 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.

What is directional selection quizlet?

Directional Selection. Occurs when individuals of one extreme of the range of characteristic are selected for. Usually occurs when the environment is changing. Example of Directional Selection. Insecticide use will select for individuals that are resistant.

Which is the best example of disruptive selection?

Disruptive Selection Example Spadefoot toad tadpoles -variation in what they eat Stabilizing Selection Acting against the extreme phenotypes and favoring the average. Example of Stabilizing Selection Birth Weight Disruptive Selection Extreme phenotypes favored over intermediates, leading to selection against average phenotypes.

Which is the best description of directional selection?

Directional, Stabilizing, and Disruptive Selection Biology. form of natural selection in which individuals at one end of a distribution curve have higher fitness than individuals in the middle or at the other end of the curve.

Which is the best description of stabilizing selection?

Stabilizing Selection. form of natural selection in which individuals near the center of a distribution curve have higher fitness than individuals at either end of the curve. Disruptive Selection. natural selection in which individuals at the upper and lower ends of the curve have higher fitness than individuals near the middle of the curve.
