Did you watch that movie "The Island?" Clones were being raised for body part harvesting for the original person who was cloned. Always in our faces. The DNA mining would be a lot simpler and the tech is there. Could use the DNA databases of the likes of Ancestry.com. Would be a good way to increase one's income....and that is why I would never, ever submit a sample to any of these purported geneology trackers. They are not there to help you find out who you are, they are there for them to find out who you are and who your DNA is compatible with.
