Will redheads become extinct?
Redheads currently make up 2 percent of the world's population, but some genetics scientists are predicting they could be extinct within 100 years.

This is due to global intermingling. Even though it only takes one red-haired parent to produce ginger-headed babies, two redheads obviously create a much stronger possibility. But if people are meeting and having children with people from all over the world, the chances of redhead gene carriers meeting and having children is getting smaller.

But don't feel too sorry for your redheaded friends just yet. Some scientists say that the redhead gene can lay dormant for generations before returning — which could lead to two very surprised parents!
