Question

a flash flood carried a raft of amazon ants away from their original population. there is enough distance between the two groups, that they will never meet in nature again. what type of reproductive barrier is this? gametic isolation behavioral isolation geographic isolation temporal isolation

Explanation:

To determine the reproductive barrier, we analyze each option:

• Gametic isolation: Involves gametes not fusing, not related to distance.
• Behavioral isolation: Due to different mating behaviors, not distance.
• Geographic isolation: Occurs when physical distance (like a flood creating separation) prevents populations from meeting. This matches the scenario.
• Temporal isolation: Due to different breeding times, not distance.

Answer:

C. geographic isolation
