Ancestery.com is a service that can analyze your DNA and supposedly let you know your genetic heritage. Meaning did your relatives come from ireland, africa, russia; and what kind of ancestry you are percentage wise based on your DNS from a spit test.
Me being a skeptic who wants to believe but needs some sort of believable evidence first decided to do a blind test. Meaning, I provided as little information as I could about me and my relatives with a goal of letting the DNA analysis stand on its own. Of course I new some basic heritage facts, but I wanted to see if the DNS analysis matched what I new for fact. or if they are just logically guessing based on strand matches.
