We are a genetic jungle, a web so to speak of all our ancestors and their history of illnesses and perks. We may have recessive or dormant genes but they make up our genetic history.
Humanity has come out of Africa and in doing so has mated with similar species like that of the Neanderthal.
An ancestry genetic DNA test would give us a broader indication of the route travelled by our ancestors and an insight into the genetic network or our self.
I think those people who stand on ceremony and think they are better than a coloured person should perhaps do an ancestry DNA test it may add a very colourful answer to those who are rather biased and discriminative in their view.
We are a melting pot of genetics and our history upon the evolutionary path is a story to unfold.
