Haplogroup Q-NWT01
human Y-chromosome DNA haplogroup
Haplogroup Q-NWT01 is a subclade of Y-DNA Haplogroup Q-MEH2. Haplogroup Q-NWT01 is defined by the presence of the F746/NWT01 Single Nucleotide Polymorphism (SNP).
Distribution
Q-NWT01 has descendants in the Northwest Territories of modern Canada. It was in these populations that it was discovered.
The Americas
Q-NWT01 is present in pre-Columbian populations in the Canadian Northwest. However, subsequent genetic studies have indicated that samples previously reported as Q-NWT01 within Eskimo-Aleut populations are more likely to belong to the Q-B143 subclade. It also has been found in a specimen of the Saqqaq culture of prehistoric Greenland.
Asia
Because few samples from Asia have been tested for this lineage, its frequency there is uncertain. However, haplogroup Q-M120 is spread widely in Asia, from Azerbaijan and Kalmykia in the west to Japan in the east and from Mongolia in the north to Brunei in the south, and the entire Q-M120 clade has been determined to be a subclade of Q-NWT01. In addition, Y-DNA that belongs to the Q-B143 subclade like the Saqqaq specimen from Greenland has been found in Koryaks.
The public source identifies “Haplogroup Q-NWT01” as human Y-chromosome DNA haplogroup. This brief keeps that definition visible, then builds a research path around Haplogroup, Q-NWT01 and human.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Haplogroup Q-NWT01”, the useful work is to connect “human Y-chromosome DNA haplogroup” to the records capable of establishing context and consequence.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 2, 2026. The linked authority identifier is Q5651941. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
