Haplogroup A2a3 is a branch on the maternal tree of humanity.
Haplogroup A8a1 is a branch on the maternal tree of humanity.
We addressed the genetic origin of 373 individuals from 22 Turkic-speaking populations, representing their current geographic range, by analyzing genome-wide high-density genotype data.
In this study we evaluated migration models to the Americas by using the information contained in native mitochondrial genomes (mitogenomes) from North America.
Through extended survey of mitochondrial DNA (mtDNA) diversity in the Nganasan, Yukaghir, Chuvantsi, Chukchi, Siberian Eskimos, and Commander Aleuts, we filled important gaps in previously unidentified internal sequence variation within haplogroups A, C, and D, three of five (A-D and X) canonical mtDNA lineages that defined Pleistocenic extension from the Old to the New World. Overall, 515 mtDNA s
