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 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 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).
Y chromosome haplogroup distribution of Turkish people [4] A 2021 study which looked at whole genomes and whole-exomes of 3,362 Turkish people found that the most common Y chromosome haplogroups were J2a, R1b, and R1a (18.4%, 14.9%, and 12.1% respectively). Haplogroups C-M130 and O3 ranged from 8.5% to 15.6%.
R-L2 is a human Y-chromosome DNA haplogroup, characteristic of a part of the inhabitants of Italy and Western Europe in general. R-L2 is thought to have originated around the Alps or southern Rhine, additionally, due to R-L2 having split off of R1b-U152 relatively early and it being a major branch, R-L2 carriers were largely contemporary with R-U152 carriers leading to R-L2 also having ...
The table below shows the human Y-chromosome DNA haplogroups, based on relevant studies, for various ethnic [dubious – discuss] and other notable groups from Europe.The samples are taken from individuals identified with the ethnic and linguistic designations shown in the first two columns; the third column gives the sample size studied; and the other columns give the percentage for each ...
