Q: Keith is a zoologist. He studies large predators. Last year, he was studying different species of lions. First, he visited the Gir forest in India. There he found the Asiatic Lions.

There he found that the African Lions were not forced to mate with close relatives due to their large number. Which place would see more inbreeding depression, Gir or Serengeti?
