Native American DNA
Origin and Evolution of Native American mtDNA Variation: A Reappraisal
Sorry about the paste format but, what I want to point out is that Schlors, scientist base Native American DNA in this study of MTDNA of this study, of Eskimos, Yakima , northwest Induansand Nadene aka Navaho, the coastal Indians especially, Atlantic and Gulf Coast or considered too admired because of the results not matching the status quo. I will post more about that.
The timing and number of prehistoric migrations in- volved in the settlement of the American continent is subject to intense debate.

D9S919 allele does not fall into the Low Marker Resolution Test category. It is a standalone test of a single SNP, the results of which are definitive.
35 The D9S919 marker is the same as marker D9S1120 as published in the 2007/2008 papers as referenced. The D9S1120 label was officially depreciated as the D9S919 marker name was already in use, per Thomas Krahn at Family Tree DNA.

for Native ancestry, whether they realize it or not. The removal known as the “Trail of Tears” occurred in the mid-1830s. By that time, most Native descendants were admixed and were not required to move. Those that were not significantly admixed and were tribally affiliated were required to remove west of the Mississippi. Records of the families who removed generally exist. Records of those who died in route do not. We can presume that those who did not remove were already significantly admixed, probably 75% or more, causing them to be light skinned enough to escape the removal. This pushes the full blooded Native ancestor back at least 2 additional generations, or born in about 1760, into the 7th generation or further where each ancestor contributed less than 1% of our DNA. To show 10% Native ancestry today, we would need ten Native 6th or 7th generation grandparents.
‟s unfortunate that with both 23andMe and deCODEme one has to extrapolate Native ancestry based upon an Asian heritage designation as compared with the HapMap grouping of 45 Han Chinese. This group is exceptionally small and could lead to at least partially incorrect ethnicities, especially for people with German, Polish or eastern European ancestry that might incorporate the Mongol, Magyar or Hun peoples. Both of these companies have the potential to provide a much better ethnic analysis with the size and diversity of their data bases.
