A female bison and male bison from different populations are brought together by researchers for breeding. The resulting offspring are all sterile. This is most likely because the bison no longer share the same:
Explanation
Answer: E, species. When animals are bred from different species, they often give rise to offspring that are sterile.
Key Takeaway: At first glance, it appears that all of the answers to this question are correct, since animals that share different orders or classes also share different species. The difference is that animals must share at least the same genus in order to be cross-bred. Therefore, animals can share the same genus but share a different species.
