Best answer: The world is full of mutts. I can remember back when I was a kid (I am 83) there were kids who would say, "I am a full blooded such and such." Probably their own parents didn't know who were all of their 8 great grandparents. Nations have invaded and occupied others and the original population didn't get up and run away. Over time, they assimilated with the new comers. New nations have been created out of old nations. 18% can go back several generations. There are areas where the borders of China and Burma are attached. Persons from China could have immigrated to Burma and intermarried with some of your Burmese ancestors.
They use Autosomal DNA along with Mitohondrial for the overall testing and Autosomal is not so simple. It is what most of your DNA is. You got it 50% from each of your parents but not 25% from each of your 4 grandparents. The reason why when your parents passed on Autosomal from their parents to you it went through "meoisis" where it was randomly jumbled and recombined. So you and your siblings got different chunks of Autosomal DNA from your parents. That means if you and a full sibling were tested by the same company at the same time, the results will not be exact. They don't explain this in their ads and promotions for the tests. Understand "meoisis" has been going on in your ancestry from the beginning. This means you might have an ancestry but not the DNA from that ancestry but your brothers or sisters can have the DNA.
Another thing, the only thing companies can do is match you with population groups in their database and each company has its own database of population groups. Go to different companies and get different results. People ask us which is the best company to use and my reply is, it is the one that has the population groups that best match your ancestry and there is no way we or even you can know that. If you knew that much, why take the test.
It has also been reported if you are tested by a company and go back sometime later and have them retest you, by that time they have received more populaiton groups that can alter your picture.
The real value of genealogy DNA testing is if you are into traditional genealogy work using documents and records and the company you choose can detect from your DNA that probably some persons they have tested are related to you, maybe a few generations back, and they notify you of those people and you make contact with them, you can collaborate your information with them. They might have discovered ancestors and records you haven't and you might have discovered records and ancestors they haven't.
