(24,128 posts)I'm not sure that scientists have gotten so far as to ferret out genetics of Native American tribes. If they have been able to do so to some extent, it wouldn't surprise me. The technology is still in its infancy. Also, some tests are more thorough/expensive than others.
DNA testing can be very revealing compared to the accounts your relatives (even those into online genealogy), genealogical databases, or written records have conveyed to you.
My brother did a spit test recently, looking for some kind of "exotic" (i.e. nonwhite) result. He didn't get that, but the scientific result he got was a far cry from what my other brother swore to when he searched names via online genealogy sites.
The more people are tested, the better the tests are refined. Again, this technology is very new, relatively speaking. From what I've read about these tests so far, results between siblings can vary in terms of percentages but will still have the same components.
