I got my DNA done just because it is amazing that it can solve cases. I found out my father was not my father. I wish the day would come that DNA was taken at birth it would help so much.

How in the heck can a Y chromosome be linked to someone's last name? They pull the Y chromo out of the DNA and just like that link it to someone's last name? More has to be explained for that to make sense.
