Final answer:
Cheetahs share a common ancestor with other large cat species and have experienced a genetic bottleneck event, resulting in a lack of genetic diversity.
Step-by-step explanation:
The lack of genetic diversity observed in cheetahs implies that they share a common ancestor with other large cat species. This is evident by the fact that cheetahs today share 99% of the same genes. The high level of genetic similarity suggests that cheetahs have gone through a genetic bottleneck event in their history, leading to a reduction in genetic variation and a smaller gene pool.
