Haplogroup R-L295 also known as R2a1 is a Y-chromosome haplogroup characterized by genetic marker L295, which has been found in South Asia, Anatolia, Arabian Peninsula, Europe and Central Asia. Subclades Paragroup R-L295* Paragroup is a term used in population genetics to describe lineages within a haplogroup that are not defined by any additional unique markers. They are typically represented by an asterisk (*) placed after the main haplogroup. Y-chromosomes which are positive to the L295 SNP and negative to the L294 SNP, are categorized as belonging to Paragroup R-L295*.

Haplogroup R2a (Y-DNA)
Haplogroup R2a, or haplogroup R-M124, is a Y-chromosome haplogroup characterized by genetic markers M124, P249, P267, L266, and is mainly found in South Asia as well as in Central Asia, Caucasus, Southwest Asia, and the Arab countries with low frequencies. Term history Haplogroup R2a is also known as haplogroup R-M124. The first reference to the newly defined haplogroup, "R-M124", was on 25 August 2010.

Haplogroup R-U106
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 (h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haplogroup R-M479
Haplogroup R2, or R-M479, is a Human Y-chromosome DNA haplogroups, Y-chromosome haplogroup characterized by genetic marker M479. It is one of two primary descendants of Haplogroup R-M207 (Y-DNA), Haplogroup R (R-M207), the other being Haplogroup R-M173 (Y-DNA), R1 (R-M173). R-M479 has been concentrated geographically in South Asia and Central Asia since prehistory. It appears to reach its highest levels among the Burusho people in North Pakistan.Julie Di Cristofaro , Erwan Pennarun , Stéphane Mazières, Natali ...

Haplogroup R-M420
Haplogroup R1a, or haplogroup R-M420, is a human Y-chromosome DNA haplogroup which is distributed in a large region in Eurasia, extending from Scandinavia and Central Europe to southern Siberia and South Asia. While R1a originated c. 22,000 to 25,000 years ago, its subclade M417 (R1a1a1) diversified c. 5,800 years ago. The place of origin of the subclade plays a role in the debate about the origins of Proto-Indo-Europeans. The SNP mutation R-M420 was discovered after R-M17 (R1a1a), which resulted in a reorganization of the lineage in particular establishing a new paragroup (designated R-M420*) for the relatively rare lineages which are not in the R-SRY10831.2 (R1a1) branch leading to R-M17. Origins R1a origins The split of R1a (M420) is computed to c. 22,000 or 25,000 years ago, which is the time of the last glacial maximum. A 2014 study by Peter A. Underhill et al., using 16,244 individuals from over 126 populations from across Eurasia, concluded that there was "a compelling ...

Haplogroup R-M207
Haplogroup R, or R-M207, is a Y-chromosome DNA haplogroup. It is both numerous and widespread amongst modern populations. Some descendant subclades have been found since pre-history in Europe, Central Asia and South Asia. Others have long been present, at lower levels, in parts of West Asia and Africa. Some authorities have also suggested, more controversially, that R-M207 has long been present among Native Americans in North America – a theory that has not yet been widely accepted. According to geneticist Spencer Wells, haplogroup K, from which haplogroups P and Q descend, originated in the Middle East or Central Asia. "Given the widespread distribution of K, it probably arose somewhere in the Middle East or Central Asia, perhaps in the region of Iran or Pakistan." However, Karafet et al. (2014) proposed that "rapid diversification ... of K-M526", also known as K2, likely occurred in Southeast Asia (near Indonesia) and later expanded to mainland Asia, although they could ...

Haplogroup R-M173
Haplogroup R1, or R-M173, is a Y-chromosome DNA haplogroup. A primary subclade of Haplogroup R (R-M207), it is defined by the SNP M173. The other primary subclade of Haplogroup R is Haplogroup R2 (R-M479). Males carrying R-M173 in modern populations appear to comprise two subclades: R1a and R1b, which are found mainly in populations native to Eurasia (except East and Southeast Asia). R-M173 contains the majority of representatives of haplogroup R in the form of its subclades, R1a and R1b (, , and ). Structure Origins The origins of haplogroup R1 remain unclear. It and its sibling clade R2 (R-M79) are the only immediate descendants of Haplogroup R (R-M207). R is a direct descendant of Haplogroup P1 (P-M45), and a sibling clade, therefore, of Haplogroup Q (Q-M242). No examples of the basal subclade, R1* have yet been identified in living individuals or ancient remains. However, the parent clade, R* was evidently present in upper paleolithic-era individuals (24,000 years ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Haplogroup R-M167
In human genetics, Haplogroup R-M167 (R1b1a1a2a1a2a1b1a1) is a Y-chromosome haplogroup which is a subdivision of Haplogroup R-DF27 and the wider haplogroup R-M269 (more specifically, its subclade R-) defined by the presence of the marker M167 (also known as SRY2627).ISOGG tree as of 2017isogg.org It arose comparatively recently, after the beginning of the European Bronze Age, and is mostly prevalent in the population of the Pyrenees region. Distribution The first author to test for this marker (long before current haplogroup nomenclature existed) was Hurles in 1999, who tested 1158 men in various populations. He found it relatively common among Basques (13/117: 11%) and Catalans (7/32: 22%). Other occurrences were found among other Spanish, Béarnais, other French, British and Germans. In 2000 Rosser et al., in a study which tested 3616 men in various populations also tested for that same marker, naming the haplogroup Hg22, and again it was found mainly among Basques (19%), in ...

Haplogroup R-L21
R-L21 or R1b1a2a1a2c, also known as R-M529 or R-S145, is a Human Y-chromosome DNA haplogroup. It is often linked to the Celtic peoples, and their migrations into Western Europe, during the Bronze and Iron Ages. One subclade, R-DF13 is numerically dominant amongst both bearers of R-L21 in general, and among living males in England, Ireland, Scotland, and Wales. Origin R-L21 is likely a haplogroup belonging to the Celts, whose ancestors (Proto-Indo-Europeans) migrated to Western Europe during the Bronze Age, populating the majority of what is now Ireland, Britain, North-West France (Armorica), and North-West Iberia. The marker is also found to a lesser extent in the remainder of France, western Switzerland, the Low Countries, northwestern Germany, Norway and Denmark. Current dispersion Currently this haplogroup is mostly found among the inhabitants of Ireland and Great Britain, but is also found in Brittany, northern France, modern Northern Portugal, Galicia and Asturias i ...

Human Y-chromosome DNA Haplogroups
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 of A ...
