Haplogroup Q-L804 is a subclade of Haplogroup Q-L54. Currently Q-L804 is Q1b1a1b below Q1b-M346.[1] 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.[2] Later studies completed the genetic bridge by determining that Q-L804 is related to Q-M242 populations of Native Americans (Q-M3) and Siberian populations of the Selkup and Ket people (Q-L54*xM3).[3] [4]Origin and distributionThe origin of Haplogroup Q-L804 is uncertain. However it is likely to have originated in Beringia (North East Siberia) c. 15000 to 17000 yBP since it is closely linked to Q-M3 and to other haplogroups linked to the indigenous peoples of the Americas (over 90% of indigenous people in Meso & South America). Today, Q-L804 is found mainly in Norway and Sweden and in regions of North West Europe of Viking Age Expansion (British Isles, Atlantic Isles, Northern Germany, Normandy and Poland). The Q-L804 is also found among descendents of Scandinavian immigrants to North America. Haplogroup Q-L804 is defined by the presence of the (L804) single-nucleotide polymorphism (SNP). Q-L804 occurred on the Q-L54 lineage roughly 10-15 thousand years ago as the migration into the Americas was underway. It is likely that the split between Q-M3 and Q-L804 happened in the ancestors of the indigenous peoples of the Americas. North EuropePopulations carrying Q-L804 are extremely thinly distributed throughout Northern Europe and among recent North European immigrants to North America. Since the discovery and definition of Q-L804 in 2014, three main subclades of Q-L804 bearing populations have been discovered in North Europe. The Q-Y9052 , the Q-JN14 and Q-Y7582. Of these three branches Q-JN14 has the widest distribution, ranging from Poland to Iceland, British Isles and France. Q-L804 is one of two subclades known as Q Nordic among genealogical communities. The Q-L527 is the other subclad of the Q Nordic. Subclade distributionQ-Y9052 Y9052 This lineage is found in Sweden, Norway and Germany. Origin: Probably Scandinavia approximately 3,000 years ago. This lineage was discovered by citizen scientists. Q-JN15 It has been found in Norway, Iceland, British Isles, Germany, France and Poland. Origin: Probably Scandinavia approximately 3,000 years ago. This lineage was discovered by citizen scientists. Q-Y7582 This lineage has been found in Scotland, Iceland and England. Origin: Probably Scandinavia approximately 3,000 years ago. This lineage was discovered by citizen scientists. Associated SNPsQ-L804 is defined by the SNPs L804 and L805 and E324. Phylogentic tree and SubgroupsCurrent status of the polygentic tree for Q-L804 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.
