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 ...
The Y haplogroup of Richard III, last king of the House of York and last of the House of Plantagenet, was identified as Y-DNA G-P287, in contrast to the Y haplotypes of five of the putative modern relatives, descendants of Henry Somerset, 5th Duke of Beaufort, of whom four belong to haplogroup R1b-U152 (x L2, Z36, Z56, M160, M126 and Z192) and ...
Haplogroup R1b is also found at various frequencies in many different populations near the Ural Mountains and Central Asia, its likely region of origin. There may be a correlation between this haplogroup and the spread of Centum branch Indo-European languages in southern and western Europe. For instance, the modern incidence of R1b reaches ...
Like other Western Europeans, among Spaniards and Portuguese the Y-DNA Haplogroup R1b is the most frequent, occurring at over 70% throughout most of Spain. [70] R1b is particularly dominant in the Basque Country and Catalonia, occurring at rate of over 80%. In Iberia, most men with R1b belong to the subclade R-P312 (R1b1a1a2a1a2; as of 2017).
Haplogroup R1b is dominant throughout Western Europe. While it was once seen as a lineage connecting Britain and Ireland to Iberia, where it is also common, it is now believed that both R1b and R1a entered Europe with Indo-European migrants likely originating around the Black Sea ; [ 8 ] R1a and R1b are now the most common haplotypes in Europe.
Haplogroup R1b is the dominant haplogroup of Western Europe and is also found sparsely distributed among various peoples of Asia and Africa. 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.
Distribution of the R1b haplogroup in Europe. Many Italians, especially in Northern Italy and Central Italy, belong to Haplogroup R1b, common in Western and Central Europe. The highest frequency of R1b is found in Garfagnana (76.2%) in Tuscany and in the Bergamo Valleys (80.8%) in Lombardy.
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 . It underwent intensive research and was previously classified as R1b1a2 (2003 to 2005), R1b1c (2005 to 2008), R1b1b2 (2008 to 2011) and R1b1a1a2 (2011 to 2020).
