Haplogroup Q-L54
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] |
Haplogroup Q-L53 (Y-DNA)
Q-L53 is a subclade of haplogroup Q-M346. Q-L53 is defined by the presence of the L53 Single Nucleotide Polymorphism (SNP). Distribution Q-L53 has descendants across much of Eurasia and in the pre-Columbian Americas. It is the parent of the major Haplogroup Q-L54 branch. Associated SNPs Q-L53 is currently defined by the L53 SNP as well as the L55, L213, L331, L475, and L476 SNPs.

Haplogroup Q-L568 (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 el, ἁπλοῦς, ''haploûs'', "onefold, simple" and en, group) is a group of similar haplotypes that share a common ancestor with a single-nucleotide polymorphism mutation. More specifically, a haplogroup is a combination of alleles at different chromosomal regions that are closely linked and that 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 ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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.

Haplogroup Q-M346 (Y-DNA)
Haplogroup Q-M346 is a subclade of 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 at the Genomic Research Center's Draft treProposed Treefor haplogroup Q-M346.

Haplogroup Q-M323 is a subclade of Y-DNA Haplogroup Q-M346. Haplogroup Q-M323 is defined by the presence of the M323 Single Nucleotide Polymorphism (SNP). Distribution Q-M323 was discovered in the Yemeni Jewish population. ''Q-M323 in 3/20 = 15% of a sample of Yemenite Jews.'' In the time since its discovery, it has not been detected in other populations. It could then be exclusive to this population. Associated SNP's Q-M323 is currently defined by the M323 SNP.

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-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 north-east Eurasia. Distribution Q-M120 has descendants in modern populations across eastern Eurasia. 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. Asia Q-M120 is present in Eastern Asia and may trace its origin to East Asia. It has been found at low frequency in samples of Han Chinese, Dungans, Hmong Daw in Laos,Cai X, Qin Z, Wen B, Xu S, Wan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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. The Americas Q-L275 has not been identified in pre-Columbian groups in the Americas. Potential sources in indigenous populations are European colonists and religious missionaries. Asia East Asia South Asia The problematic phylogeny sampling of early studies has been demonstrated by subsequent studies that have found the Q-M378 descendant branch in South Asia. West Asia According to Behar et al. 5% of Ashkenazi males belong to haplogroup Q. This has subsequently been found to be entirely Q-L275's Q-M378 subclade and is further restricted to the Q-L245 branch. Europe Subclade Distribu ...

Haplogroup Q-M242 (Y-DNA)
Haplogroup Q or Q-M242 is a Y-chromosome DNA haplogroup. It has one primary subclade, Haplogroup Q1 (L232/S432), which includes numerous subclades that have been sampled and identified in males among modern populations. Q-M242 is the predominant Y-DNA haplogroup among Native Americans and several peoples of Central Asia and Northern Siberia. Origins Haplogroup Q-M242 is one of the two branches of P1-M45, the other being R-M207. P1, as well as R* and Q* were observed among Ancient North Eurasians, a deeply European hunter-gatherer related population. Q-M242 is believed to have arisen around the Altai Mountains area (or South Central Siberia), approximately 17,000 to 31,700 years ago. However, the matter remains unclear due to limited sample sizes and changing definitions of Haplogroup Q: early definitions used a combination of the SNPs M242, P36.2, and MEH2 as defining mutations. Technical specification of mutation The polymorphism, “M242”, is a C→T transition resi ... [...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 mutations in the non- recombining portions of DNA from the male-specific Y chromosome (called Y-DNA). Many people within a haplogroup share similar numbers of short tandem repeats (STRs) and types of mutations called single-nucleotide polymorphisms (SNPs). The human Y-chromosome accumulates roughly two mutations per generation. "one mutation in every 30 million base pairs" Y-DNA haplogroups represent major branches of the Y-chromosome phylogenetic tree that share hundreds or even thousands of mutations unique to each haplogroup. The Y-chromosomal most recent common ancestor (Y-MRCA, informally known as Y-chromosomal Adam) is the most recent common ancestor (MRCA) from whom all currently living humans are descended patrilineally. Y-chromosomal Adam is estimated to have lived roughly 236,000 years ago in Africa. By examining other bottlenecks most Eurasian men (men from populations outside ...
