Solution
Correct Answer:
Allopatric
- Speciation: The formation of new and distinct species in the course of evolution.
- Allopatric Speciation: Occurs when a population is divided by a physical, geographic barrier (like a mountain range, river, or ocean).
- Divergence: Once separated, the two groups cannot interbreed. They accumulate different mutations and face different natural selection pressures until they become separate species.
- Sympatric Speciation: Occurs within the same geographic area due to other factors like polyploidy or behavioral changes.
This easy difficulty biology question is from the chapter genetics and evolution, covering the topic of speciation. It appeared in the 2025 exam.
