Haplogroup R1b (R-M343), previously known as Hg1 and Eu18, is a human Y-chromosome haplogroup.. It is the most frequently occurring paternal lineage in Western Europe, as well as some parts of Russia (e.g. the Bashkirs) and across the Sahel in Central Africa, namely: Cameroon, Chad, Guinea, Mauritania, Mali, Niger, Nigeria and Senegal (concentrated in parts of Chad with concentration in the ...
Haplogroup R-M269 is the sub-clade of human Y-chromosome haplogroup R1b that is defined by the SNP marker M269.According to ISOGG 2020 it is phylogenetically classified as R1b1a1b.
One subclade of haplogroup R1b (especially R1b1a2), is the most common haplogroup in Western Europe and Bashkortostan , while a subclade of haplogroup R1a (especially haplogroup R1a1) is the most common haplogroup in large parts of South Asia, Eastern Europe, Central Asia, Western China, and South Siberia.

Its subclade R1b1a2 (M269) is the haplogroup that is most commonly found among modern Western European populations, and has been associated with the Italo-Celtic and Germanic peoples. Haplogroup R1 (M173) Found throughout western Eurasia. Haplogroup R1a (M420) Found in Central Asia, South Asia, and Central, Northern and Eastern Europe, Balkans
According to a 2017 article published in Springer Nature entitled, Analysis of the R1b-DF27 haplogroup shows that a large fraction of Iberian Y-chromosome lineages originated recently in situ, DF27 was found in frequences of 40% in the general population of the Iberian Peninsula and in particular spikes at 70% among the Basques.
Based on the unverified images, iGENEA claimed that Tutankhamun belonged to Y-DNA haplogroup R1b1a2, [59] [60] a claim that was rejected as "unscientific" by members of the team that had actually analysed the Eighteenth Dynasty mummies. The original researchers also stated they had not been consulted by iGENEA before it published the haplogroup ...
In human population genetics, Y-Chromosome haplogroups define the major lineages of direct paternal (male) lines back to a shared common ancestor in Africa. Men in the same haplogroup share a set of differences, or markers, on their Y-Chromosome, which distinguish them from men in other haplogroups.
The genetic divergence of R1a (M420) is estimated to have occurred 25,000 [2] 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 case for the Middle East, possibly near present-day Iran, as the geographic origin of hg R1a".
