Question

Quizplus · Accepted Answer

The question mentions both "behavioral and _______ isolation," with the blank representing the type of isolation. Among the choices given, the only one that fits with "behavioral" is "temporal." Temporal isolation involves differences in the timing of reproductive behavior, such as different mating seasons, and can lead to the formation of distinct species. Autopolyploidy involves changes in chromosome number within a single species and can also contribute to reproductive isolation, but it is not mentioned in the question stem. Allopatric isolation involves physical separation of populations, gametic isolation involves incompatibility between gametes, and mechanical isolation involves physical differences that prevent successful mating.
