Thanks for your insight. How do you know for a fact that there is not a pure race? I guess, ancestry.com is wrong then? That would not make sense. Based on what they say, it makes sense. East Asians and Polynesians prefer not to mix. And, maybe way back they did mix but because they've stayed within their race for so long, their "mix" gene percentage are so small that it doesn't show up at all on the DNA tests.
Where do you get this idea of a "pure" race from? With maybe the exception of the Adaman islanders (who may not have mixed with any surrounding peoples, still probably have dna from Neanderthals or Denisovans), everyone else is mixed. Here's how "pure" East Asians are:

The different colors are DNA Haplogroups (
https://en.wikipedia.org/wiki/Haplogroup ), mtDNA for the women and yDNA for the men. Unless you see a group of people with one single color, it means they have multiple ancestries. Here's one for Hmong and Mien women, but it's not so nice and visual:
http://mbe.oxfordjournals.org/content/22/3/725.fullHaplogroups to the right, 1-17 for each group of Hmong or Mien.
So, having said that, if I have Polynesians in my DNA, it could either mean that Hmong and Polynesians were once one race or that they didn't break down that gene far enough to see the variations between the two.
No, that's not what it means at all. You have like the most basic understanding of genetics (honestly, basic might be even too much of a stretch). I suggest you refrain from coming to wild conclusions.
Don't make this topic a debate about where Hmong come from. Keep it at the DNA level. I've done enough research about Hmong people and it hasn't really taught me much except that I'm Hmong and that I want to know the DNA of a Hmong person, 'cause I'd like to know what other ethnicity I have in me or if Hmong is its own ethnicity (hoping to figure this out).
Well, you didn't research in the right direction. Yes, there is not a lot of info, but there's enough; enought for me to tell you where hmong people come from...I can even tell you how they got there, from where and from who. That information is just as available to me as it is to you.
It might be hard for some to understand unless you've been in my shoes but I had someone asked me if I was Hawaiian and someone else asked if I was Native American. I have round eyes (or less thin and slanted eyes) and olive skin. I look less Chinese, Laos, and Thai than I do Polynesian. I've always wondered why they would even assume I wasn't just East Asian. Even my own daughters tell me I don't look Asian and that I do look Hawaiian or Native American and I've never told them about the people who thought I was those ethnicity. My DNA report has answered an interesting question but again, I'm not done searching.
You're making another wrong assumption: genes do not completely correlate with phenotype (phenotype means physical appearance). Go back to the chart above for the Men in east asia. Tibetans ("Tib" in the chart) have nearly 90% yDNA D (the yellow color). Know who else has 90% or more yDNA D? Adaman islanders. According to your logic, they should look the same. You tell me, do they look the same?
