The boy Anzick-1, who lived 12,600 years ago and was found in the state of Montana, has a Y-chromosome that refers to haplogroup Q-M971 (Q-L54*(xM3)).
[3] Q-L330 is also found in some men with Romaniote Jewish paternal lines from Greece.
[4] Haplogroup Q‐L54 is dominant in two North Siberian populations, the Kets and Selkups, with frequencies of 97.7% and 66.7%, respectively.
Current status of the polygenetic tree for Q-L54 is published by Pinotti et al. in the article Y Chromosome Sequences Reveal a Short Beringian Standstill, Rapid Expansion, and early Population structure of Native American Founders.
