As for the native American DNA...i have 100 percent proof I am 1/8 Sioux and the ancestry test came back not mentioning that. I did a little digging and it seems the tribes told them no way when it came to giving them samples to use.
So it sounds like their tests are not as accurate as they want us to think. It's only as accurate as the data they have to work with like any other piece of science.
