Question

what type of isolation occurs when the timing of reproduction is different between two populations?
a. geographic
b. temporal
c. behavioral
d. genetic

Explanation:

To solve this, we analyze each option:

• Option A (Geographic): Involves physical separation (e.g., mountains, oceans) preventing mating. Not related to timing of reproduction.
• Option B (Temporal): Temporal isolation is defined as the isolation that occurs when two populations reproduce at different times (e.g., different breeding seasons). This matches the description in the question.
• Option C (Behavioral): Involves differences in mating behaviors (e.g., courtship rituals) preventing mating. Not about timing.
• Option D (Genetic): Refers to genetic differences leading to isolation, not related to timing of reproduction.

Answer:

B. Temporal
