The quick answer is the test are looking at different things. One test is for
mitochondrial DNA. That traces back to one of the many daughters of Eve and
is always passed from mother to her child. The Y test traces the chromosome
that produces the masculine gender. It goes from a father to his son.
However, the DNA Print looks at a number of different sites that come from
the DNA combined from both parents. When you get back 5 or 6 generations the
DNA is so combined the part that proves Native American ancestry might not
show in the results.
