Analysis of complete Y-chromosome sequencing of Paleo-Eskimo of the Saqqaq culture were first published by Rasmussen et al., 2010. The authors identified the sample as belonging to Y-chromosome haplogroup Q1a-MEH2.
In 2014 the data was reanalyzed by the Y-chromosome Q haplogroup project at YFull data interpretation service and placed in the YFull experimental Y-chromosome tree. The Saqqaq data was found to belong to Q-F746 / NWT01.
Q-F746 / NWT01 is found among the indigenous population of northwestern Canada and Alaska. Dulik et. al., 2012, state in their paper Q-F746 is found in 45 to 60% of sampled Inupiat (Alaskan Eskimo) and Inuvailuit (Inuit of Northwest Canada).
New light has been shed on the origin of the Paleo-Eskimo Saqqaq with the release from the Estonian Biocenter data, which was published in the paper Karmin et al., 2015 (A recent bottleneck of Y chromosome diversity coincides with a global change in culture).
Complete sequencing Y-chromosome data from four samples from Koryak village of Evensk North Eastern District Magadan region (KrkG11, KrkG13, KrkG14, KrkG55). The four samples have 37 SNPs in common with the paleo-Eskimo sample. The resulting subclade has been assigned the label Q-YP1500 / YP11467-YP1503 in the YFull service experimental tree.
Thus, the structure of Q-F746 subclades is as follows:
Q-F746 / NWT01
……….Q-YP1500 / YP1467-YP1503 (Paleo-Eskimo and Koryak Saqqaq)
|SNP ID||Position, Build37||Ancestral||Derived|
The parallel branch Q-M120, common among the Chinese, Tibetan, Bhutanese, Koreans, Vietnamese, creates the possibility of a more detailed study of migration from Eurasia to North America across the Bering Strait and the relationship of Eurasian populations and Amerindian populations.
The ancient sampled Paleo-Eskimo of the Saqqaq culture of Greenland shares phylogeny with Koryak indigenous peoples of the Russian Far East, Alaska, Northern Canada and Greenland.
