I finally found a test which focuses more on and breaks down the Native American ancestry in DNA -- meaning the totals found in North America, South America, Arctic America and Mesoamerica as well...which is good because American Indians were spread out, not just in North America. But a vast majority of my Native heritage comes from the states.
I came back as:
1.76 north american indian
0.46 south american indian
0.61 mesoamerican
0.09 arctic american indian
For a total of 2.92 Native American blood. This number may seem small but it is significantly high for an African American; only 19 percent of us even have a full 1% NA in us, and only 5 percent of us have 2% NA blood or more.
As you can see, the thresholds are TIGHT -- 81 percent of us fall below 1% then it jumps to 5 percent of us with 2% or more. Meaning it's virtually impossible you'd find a black person (black as in predominately of African descent, as most of us are) with 5-10 Native American blood.
Whites also carry way less than they'd love to think, if any at all -- their threshold percentages are pretty much the same as ours. This is why when most of us do these DNA tests, there is no NA blood detected. So yes, even a bi-racial butterfly has very slim chances of having NA blood, because both sides of the fence carry so little, if any.
I'm not too surprised with my personal results, I mean my great grandmother's name was Chief, I should expect larger amounts than usual in my blood since the culture was obviously there just 3 generations back. However, I still find it amazing how ancestrally diverse my mothers side of the family is.
