This seems to be a recurring topic on this forum, so the new 'world9' calculator Dienekes released for his DIYDodecad program should make some people happy. By popular demand, he made a worldwide calculator, which for the first time includes Australasian and Native American reference populations. Here are the results for my parents and me:
Based on previous BGA analysis, I wasn't expecting any newly discovered Native American genetic ancestry, but it's interesting nonetheless. My dad for sure has no Native American ancestors, but his percentage is higher than my mom and me. We're Y-DNA haplogroup N, which is highest in the tribes of northern Siberia. Some of that must be bleeding over into the Amerindian component. According to a paper trail, I actually do have a Native American 8th great grandmother on my mom's side. But I haven't verified all the research, nor seen any of the original documents beyond my 5th great grandfather on that line. In any case, we obviously didn't inherit any detectable DNA from her.
As a note of caution, it's worth looking at which populations the Amerindian component peaks in. (The "Athabask" samples are also known as "Na-Dene" in some BGA analyses. One is separate from the rest, as it's clearly an outlier.)
Some of the Siberian samples have a significant percentage of the Amerindian component--as high as 22% in Chukchis! And the last population on that list is from Central Asia. Tajiks definitely have no Native American ancestry, although some Russian admixture might appear as such to the software.
In other words, even if you had 5% of the Amerindian component, it still wouldn't necessarily signify any Native American ancestry. It might be more than just noise, but only a corresponding paper trail would lend support to that interpretation. If you have 2% or less of the Amerindian component, there's no genetic evidence of any Native American ancestry.
