The cheetah gene pool is small today primarily due to multiple bottleneck events in the past, which have greatly reduced the genetic diversity within the population. Additionally, inbreeding in zoos and a lack of advantageous traits have further contributed to the small gene pool of cheetahs. This reduced genetic diversity can lead to decreased adaptability and resilience to environmental changes, making the cheetah population more vulnerable to threats such as disease outbreaks and habitat loss.
