Haplogroup R2
Haplogroup R2, or R-M479, is a Y-chromosome haplogroup characterized by genetic marker M479. It is one of two primary descendants of Haplogroup R (R-M207), the other being 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, Natalie M. Myres, Alice A.

Haplogroup R-M124 (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. Before the publication of the 2005 Y-Chromosome Phylogenetic Tree, Haplogroup R-M124 was known as Haplogroup P1 and formerly thought to be a sister clade of Haplogroup R rather than derived from it.Manoukian, Jean-Grégoire (2006),A Synthesis of Haplogroup R2 - 2006" Haplogroup R2 most often observed in Asia, especially on the Indian sub-continent and Central Asia.

Single-nucleotide Polymorphism
In genetics, a single-nucleotide polymorphism (SNP ; plural SNPs ) is a germline substitution of a single nucleotide at a specific position in the genome. Although certain definitions require the substitution to be present in a sufficiently large fraction of the population (e.g. 1% or more), many publications do not apply such a frequency threshold. For example, at a specific base position in the human genome, the G nucleotide may appear in most individuals, but in a minority of individuals, the position is occupied by an A. This means that there is a SNP at this specific position, and the two possible nucleotide variations – G or A – are said to be the alleles for this specific position. SNPs pinpoint differences in our susceptibility to a wide range of diseases, for example age-related macular degeneration (a common SNP in the CFH gene is associated with increased risk of the disease) or nonalcoholic fatty liver disease (a SNP in the PNPLA3 gene is associated with inc ...

Haplogroup R-U106 (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 (hap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haplogroup R-M420 (Y-DNA)
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-M167 (Y-DNA)
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%), i ...

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.

Haplogroup R-L21 (Y-DNA)
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 in ...
