Description
Haplogroup Q1a (F746) is the major subclade of Q1 and the primary Y-DNA lineage of Native Americans as well as some Central and South Asian populations. Q1a encompasses the Q1a3 (L54) branch which gave rise to the founding Native American Y-DNA lineages (Q-M3, Q-M346), as well as Central and South Asian Q1a sub-branches. The Q1a lineage crossed from Siberia to North America via the Beringian land bridge approximately 15,000–20,000 years ago, making Q1a carriers the patrilineal founders of the indigenous populations of the Americas. In Asia, Q1a persists at notable frequencies among Selkup, Ket, and other indigenous Siberian peoples.
Interesting Fact
Q1a (specifically the Q-M3 sub-branch) is the dominant Y-DNA haplogroup among Native Americans in North, Central, and South America, found at 60–90% frequency in many indigenous communities. This haplogroup is the patrilineal genetic signature of the people who crossed the Beringian land bridge to colonize the entire Western Hemisphere from Alaska to Patagonia — arguably one of the most dramatic migrations in human history.
