My haplogroup is estimated R1b, but Q also shows up, does that indicate my Native American heritage?
No. It is possible that two unrelated results may have experienced mutations or changes in the past which make them appear to be more closely related than they actually are. If your haplogroup is R1b, then you do not share a common ancestor with someone who is a Q for tens of thousands of years. If there is Native American ancestry somewhere else in your family tree, the test cannot pick it up.
