Question

why do disruptive selection pressures tend to favor rapid evolutionary changes? a. they result in sudden gene frequency changes. b. they eliminate extreme genetic traits. c. they select for one variation of a genetic trait. d. they result in environmental adaptation. please select the best answer from the choices provided

Explanation:

Disruptive selection favors extreme phenotypes over intermediate ones. It causes sudden shifts in gene frequencies in a population, leading to rapid evolutionary changes. Option a is correct as it accurately describes this mechanism. Option b is incorrect because disruptive selection favors extreme traits, not eliminates them. Option c describes directional selection, not disruptive selection. Option d is too general and does not specifically address why disruptive selection causes rapid change.

Answer:

A. They result in sudden gene frequency changes.
