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.

With a 95% probability, the most recent common ancestor of all members of haplogroup 6786 4439 BCE. He is the ancestor of at least 1 descendant lineage known as Q-BY1771. Descendant lineages are identified as people test their Y-DNA with the Big Y test.

History and description of Haplogroup Q (Y-chromosomal DNA) and its subclades. Haplogroup Q is a North and Central Asian lineage linked to the Huns, Mongols and Turkic people. It is also a minor Scandinavian and Jewish lineage.

Haplogroup Q-L804, also known as Haplogroup Q-M242 (Y Chromosome Consortium long-form label), is a genealogical group of lineages defined by unique genetic markers present on the Y-chromosome.

Y-haplogroup Q-L804 and Q-L527 were originally found in areas of the Nordic countries at around 1-2% of the population. For L527, the highest percentage has been found around the Götaland area of Sweden, and for L804, there is a high density in the Møre og Romsdal area of Norway.

In this study, we collected 39 samples from China and Russia, investigated 432 samples from previous studies of haplogroup Q, and analyzed the single nucleotide polymorphism (SNP) subclades Q1a1a1-M120, Q1a2a1-L54, Q1a1b-M25, Q1a2-M346, Q1a2a1a2-L804, Q1a2b2-F1161, Q1b1a-M378, and Q1b1a1-L245. Through NETWORK and …

Q-L804 and Q-L527 was in the early days of DNA-testing found in Scandinavia (Iceland, Norway and Sweden) and British Isles, then later inn all Nordic countries including Denmark and Finland. By 2019, Q-L804 and Q-L527 had also been detected in …

To assess the timing, places of origin and extent of admixture between these components, we performed an analysis of the Y-chromosome haplogroup Q, which is the only Pan-American haplogroup and accounts for virtually all Native American Y chromosomes in …

Jul 10, 2018 · Among Eurasian samples, we identified Y-chromosome branches that are most closely related to known American aborigine founding lineages, that is, Q1-L804 links to Q1-M3, Q1-L330 links to...
