Haplogroup Q-L54 (Y-DNA)
Haplogroup Q-L54 is a subclade of Y-DNA haplogroup Q-L53. Q1a3a-L54 is defined by the presence of the L54 Single Nucleotide Polymorphism (SNP). Distribution Q-L54 has descendants across Western and Central Europe, the North and East of Asia, and the Americas. It includes two of the major pre-Columbian paternal lineages in the Americas: Q-M3 and Q-M971. The boy Anzick-1, who lived 12,600 years ago and was found in the state of Montana, has a Y-chromosome that refers to haplogroup Q-M971 (Q-L54*(xM3)). Q-L54 descendant lines also include two Eurasian paternal lineages, the Central Asian Q-L330 lineage and the Scandinavian Q-L804. Q-L330 is also found in some men with Romaniote Jewish paternal lines from Greece. Q-L804 is Scandinavian and the TMRCA is just over 3000 years. Haplogroup Q‐L54 is dominant in two North Siberian populations, the Kets and Selkups, with frequencies of 97.7% and 66.7%, respectively. Associated SNP's Q-L54 is currently defined by the L54 SNP alone ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Human Y-chromosome DNA Haplogroup
In human genetics, a human Y-chromosome DNA haplogroup is a haplogroup defined by specific mutations in the non-Genetic recombination, recombining portions of DNA on the male-specific Y chromosome (Y-DNA). Individuals within a haplogroup share similar numbers of short tandem repeats (STRs) and single-nucleotide polymorphisms (SNPs). The Y-chromosome accumulates approximately two mutations per generation, "one mutation in every 30 million base pairs" and Y-DNA haplogroups represent significant branches of the Y-chromosome phylogenetic tree, each characterized by hundreds or even thousands of unique mutations. The Y-chromosomal most recent common ancestor (Y-MRCA), often referred to as Y-chromosomal Adam, is the most recent common ancestor from whom all currently living humans are descended Patrilineality, patrilineally. Y-chromosomal Adam is estimated to have lived around 236,000 years ago in Africa. By examining other population bottlenecks, most Eurasian men trace their descent ...

Haplogroup Q-NWT01 (Y-DNA)
Haplogroup Q-NWT01 is a subclade of Y-DNA Haplogroup Q-MEH2. Haplogroup Q-NWT01 is defined by the presence of the F746/NWT01 Single Nucleotide Polymorphism (SNP). Distribution Q-NWT01 has descendants in the Northwest Territories of modern Canada. It was in these populations that it was discovered. The Americas Q-NWT01 is present in pre-Columbian populations in the Canadian Northwest. However, subsequent genetic studies have indicated that samples previously reported as Q-NWT01 within Eskimo-Aleut populations are more likely to belong to the Q-B143 subclade. It also has been found in a specimen of the Saqqaq culture of prehistoric Greenland.YFull Haplogroup YTree v6.03.05 at 20 July 2018.

Haplogroup Q-M346 (Y-DNA)
Haplogroup Q-M346 is a subclade of Y chromosome, Y-DNA Haplogroup Q (Y-DNA), Haplogroup Q. Haplogroup Q-M346 is defined by the presence of the M346 Single Nucleotide Polymorphism (SNP). Origin and distribution Q-M346 was discovered in Central Asia and announced in Sengupta 2006. A latter paper suggested that its ancestral state was isolated to India, but this has since been refuted by its presence in West Asia, Europe and the Americas. Asia Q-M346 has a wide distribution across much of Asia. The Americas In the Americas, the founding paternal lineages include those who are Q-M346 but do not belong to the Q-M3 lineage. Associated SNPs Q-M346 is marked by the presence of the M346 SNP. Since the discovery of M346 several additional SNPs have been found to also be associated with Q-M346. These SNP's include: L56 and L57. These SNPs appear to be "parallel" to M346. Subgroups This is Thomas Krahn's—of the Genomic Research Center—draft treeProposed Tree for haplogroup ...

Haplogroup Q-M25 (Y-DNA)
Haplogroup Q-M25, also known as Q1a1b is a subclade or branch of human Y-DNA haplogroup Q-F1096 (Q1a1), which is, in turn, a subclade of Q-MEH2 ( Q1a). In human genetics, each Y-DNA haplogroup constitutes a biological paternal lineages back to a shared common male ancestor. Distribution Q-M25 has descendants in modern populations across all of Eurasia. Only one detailed study on the Y-DNA on Turkmens from Turkmenistan has taken place. Haplogroup Q is found in minority Turkmen tribes living in Afghanistan at percentages of about 32%,J D Cristofaro et al., 2013, "Afghan Hindu Kush: Where Eurasian Sub-Continent Gene Flows Converge", http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0076748 and another study found that 42.6% of Iranian Turkmens have haplogroup Q-M25 (also known as Q1a1b).

Haplogroup Q-B143
Haplogroup Q-B143 is a subclade of Y-DNA Haplogroup Q-NWT01. It is defined by the presence of the B143 Single Nucleotide Polymorphism (SNP). Distribution Q-B143 is primarily found among the indigenous peoples of the North American Arctic, Greenland, and Northeastern Siberia. It exhibits high frequencies among the Eskimos of Alaska, Canada, and Greenland. It also has been found in the Koryaks, Chukchi and Yukaghirs. Recent studies indicate that the previously reported Q-NWT01 in Greenland populations is more likely to belong to the subclade Q-B143. The oldest known example of Q-B143 was found in an Ancient Paleo-Siberian individual from the Duvanniy Yar site in northeastern Siberia, dating back approximately 10,000 years. A male from the Saqqaq culture, discovered in Greenland and dated to around 4,000 years ago, has been found to belong to the Q-B143 lineage.

Haplogroup Q-M120 (Y-DNA)
Haplogroup Q-M120, also known as Q1a1a1, is a Y-DNA haplogroup. It is the only primary branch of haplogroup Q1a1a (F746/NWT01). The lineage is most common amongst modern populations in eastern Eurasia. But the haplogroup might have been historically widespread in the Eurasian steppe and north Asia since it is found among Cimmerians in Moldova and Bronze Age natives of Khövsgöl. Distribution The Americas One of the 1K Genomes samples, HG01944, from Peruvians in Lima, Peru belongs to Q-M120. Q-M120 is the other branch under Q-F746. It is best known as an East Asian branch of Q. This is intriguing; if it is not a result of post-colonial admixture, it will mark a fourth or fifth Q lineage in the Americas. The branch of Q-M120 including this sample has a calculated TMRCA of 5,000 to 7,000 years, meaning that it may be the result of a later pre-Columbian immigration from North or East Asia. Grugni et al. (2019) found the presence of the Q-pre-M120 lineage, a precursor to Q-M12 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haplogroup Q-L940 (Y-DNA)
A haplotype is a group of alleles in an organism that are inherited together from a single parent, and a haplogroup (haploid from the , ''haploûs'', "onefold, simple" and ) is a group of similar haplotypes that share a common ancestor with a single-nucleotide polymorphism mutation. More specifically, a haplotype is a combination of alleles at different chromosomal regions that are closely linked and tend to be inherited together. As a haplogroup consists of similar haplotypes, it is usually possible to predict a haplogroup from haplotypes. Haplogroups pertain to a single line of descent. As such, membership of a haplogroup, by any individual, relies on a relatively small proportion of the genetic material possessed by that individual. Each haplogroup originates from, and remains part of, a preceding single haplogroup (or paragroup). As such, any related group of haplogroups may be precisely modelled as a nested hierarchy, in which each set (haplogroup) is also a subset of a sing ...

Haplogroup Q-L275 (Y-DNA)
Haplogroup Q-L275 or Haplogroup Q2 (formerly Haplogroup Q1b) is a human Y-chromosome DNA haplogroup believed to have originated in Eurasia. Haplogroup Q-L275 is defined by the presence of the L275 single-nucleotide polymorphism (SNP). Haplogroup Q-L275 can be identified through genealogical DNA testing. Distribution Q-L275 has descendants across Europe, Central Asia, and South Asia. Q-M378 is phylogeographically restricted to southwest Asia. "Only two American Y chromosomes did not cluster into the L54 sub-branch. They were both M378-positive, thus belonging to Q1b, a finding never previously reported for Native Americans. Considering that the phylogeography of this infrequent haplogroup is restricted to South West Asia 2�� 5 the most likely interpretation of this outcome is that they represent an arrival from Asia in contemporary history. For this reason the two Y chromosomes were not included in subsequent analyses." The Americas Q-L275 has not been identified in pre-Colu ...

Haplogroup Q-M242 (Y-DNA)
Haplogroup Q or Q-M242 is a Human Y-chromosome DNA haplogroup, Y-chromosome DNA haplogroup. It has two primary subclades: Q1/Q-L472 (also known as Q-MEH2) and Q2/Q-L275). These include numerous subclades that have been sampled and identified in males among modern populations. Q is the predominant Y-DNA haplogroups in indigenous peoples of the Americas, Y-DNA haplogroup among Native Americans, Swati tribe and several peoples of Central Asia and Far North (Russia), Northern Siberia. Defining mutations The polymorphism M242, is a C→T transition residing in intron 1 (IVS-866) of the DBY gene and was discovered by Mark Seielstad et al. in 2003. The technical details of M242 are: :Nucleotide change: C to T :Position (base pair): 180 :Total size (base pairs): 366 :Forward 5′→ 3′: :Reverse 5′→ 3′: Other defining SNPs unique to Q-M242 include: FGC1752, F2603/M1020, L232/S432, M1115, Y2000/FGC1757, FGC6793, Y1984/FGC1753, Y1987/FGC1754/F6492, FGC7650(H), E337/L808/CTS3 ...
