Haplogroup Q-NWT01
Possible time of origin Between 4,000 and 7,000 years ago [1]
Possible place of origin Asia or Beringia
Ancestor Q-MEH2
Descendants Q-M120[2]
Defining mutations NWT01

Haplogroup Q-NWT01 is a subclade of Y-DNA Haplogroup Q-MEH2.[1] Haplogroup Q-NWT01 is defined by the presence of the NWT01 Single Nucleotide Polymorphism (SNP).

Distribution[edit]

Q-NWT01 has descendants in the Northwest Territory of modern Canada. It was in these populations that it was discovered.[1]

The Americas[edit]

Q-NWT01 is present in pre-Columbian populations in the Canadian Northwest.[1]

Population Paper N Percentage SNP Tested
Gwich’in Dulik 2012 0/33 ~0.00% NWT01
Tłįchǫ Dulik 2012 1/37 ~2.70% NWT01
Inuvialuit Dulik 2012 25/56 ~44.62% NWT01
Inupiat Dulik 2012 3/5 ~60.00% NWT01

Asia[edit]

Because samples from Asia have not yet been tested for this lineage, its frequency there is uncertain.

Associated SNPs[edit]

Q-NWT01 is currently defined by only the NWT01 SNP. As part of the National Geographic Geno 2.0 test, this SNP is labeled F746. This is because it was independently discovered in a Q-M120 sample sequenced with next generation technology.[2] It can also be called PR4083 as it was labeled in a primate sample sequenced at Family Tree DNA's Genomic Research Center.[2]
