Genetic studies of mitochondrial DNA (mtDNA) of Amerindians and some Siberian and Central Asian peoples also revealed that the gene pool of the Turkic-speaking peoples of Siberia such as Altaians, Khakas, Shors and Soyots, living between the Altai and Lake Baikal along the Sayan mountains, are genetically closest to Amerindians.[citation needed] This view is shared by other researchers who argue that "the ancestors of the American Indians were the first to separate from the great Asian population in the Middle Paleolithic. 2012 research found evidence for a recent common ancestry between Native Americans and indigenous Altaians based on mitochondrial DNA and Y-Chromosome analysis. The paternal lineages of Altaians mostly belong to the subclades of haplogroup P-M45 (xR1a 38-93%; xQ1a 4-32%).
What DNA analysis indicated the common ancestry of the Native Americans?
****
The answer:
mitochondrial DNA and Y-Chromosome
