Problem:
In some cases two species can hybridize. For example, Tigers and lions can hybridize to produce "Ligers".
Required:
Question: Would it also be possible for humans and chimpanzees (or any other species) to hybridize ? If not, what would be the likely cause of failure?
Question: Why do some hybridization matings produce offspring, like the Liger, and some not?
Question: What mechanisms prevent hybridizations?
Explain all the answers in detail.
