Haplogroup Q1a3-M346 along with haplogroup C3-M217 are both considered indicators of Native American ancestry.
Today, members of Q-M242 are found in Siberian populations of Kets (94%), Selkups (66%), Altians (17%), and Mongolians (4%), and Native American populations including Ameridians (9%) and NaDenŽ-speaking groups (25%).
Haplogroup Q1a3-M346, a subgroup of Q-M242, is believed to be indigenous to the Americas, but some back-migration may have occurred since Q1a3-M346 can be found at very low frequencies in Northern Siberia and Central Asia. Another sublineage, Q1a3a-M3 originated about 8,000 years ago in the Americas where it is widespread throughout both continents. It is found in South American Amerind populations at 58%, NaDenŽ populations at 50%, and North American Eskimo Aleut populations at about 46%.
Haplogroup Q1a3a1-M19 is a subclade of Q1a3a-M3 and is restricted to South American populations. The Ticuna population of the upper Amazon (67%) and Wayuu population of Columbia's Caribbean coast (10%) are members of the Equatorial-Tucano linguistic family that share the Q1a3a1 haplogroup.link. gene tree q y-DNA
