Haplogroup Q-L804 (Y-DNA) is a Y-chromosome DNA haplogroup. Haplogroup Q-L804 is a subclade of Haplogroup Q-L54. Currently Q-L804 is Q1b1a1b below Q1b-M346.
In 2000 the research group at Oxford University headed by Dr. Agnar Helgason first discovered the haplotype that was much later to become known as Q-L804. In 2000 the strange haplotype was called “branch-A” (i.e. R1b-branch A) and it was found uniquely on Iceland and Scandinavia. Later studies completed the genetic bridge by determining that Q-L804 is related to Q-M242 populations of Native Americans, Turkmen (Q-M3) and Siberian populations of the Selkup and Ket people (Q-L54*xM3).
