And back you accommodated a red arch with dejected eyes, you are attractive at the rarest colour aggregate of all for animal beings.

Around 17 per cent of bodies accept dejected eyes, and back accumulated with 1-2 per cent accepting red hair, the allowance of accepting both ancestry are about 0.17 per cent. That’s 13 actor people, out of the 7.6 billion on Earth.

So with numbers this low, could redheads with dejected eyes absolutely go extinct?
