Haplogroup R-M343 (R1b): present in Bulgarians at 10.7%. [12] R1b is the most frequently occurring haplogroup around Ural and Chad, in most of western Europe and the adjacent islands. A Balkan entry of R1b into Europe is a major theory. The Bulgarian internal structure is heterogeneous and 4% of Bulgarian males carry western European subclades.
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 ...
Especially Western European R1b is dominated by specific sub-clades of R-M269 (with some small amounts of other types found in areas such as Sardinia [23] [33]). Within Europe, R-M269 is dominated by R-M412, also known as R-L51, which according to Myres et al. (2010) is "virtually absent in the Near East, the Caucasus and West Asia."
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 ...
R1 has two descendant subclades: R1a and R1b. R1a is associated with the proto-Indo-Iranian and Balto-Slavic peoples, and is now found predominantly in Central Asia, South Asia, and Eastern Europe. Haplogroup R1b is the dominant haplogroup of Western Europe and is also found sparsely distributed among various peoples of Asia and Africa.
Haplogroup R is a widely distributed human mitochondrial DNA (mtDNA) haplogroup. Haplogroup R is associated with the peopling of Eurasia after about 70,000 years ago, and is distributed in modern populations throughout the world outside of sub-Saharan Africa.
The various ethnolinguistic groups found in the Caucasus, Central Asia, Europe, the Middle East, North Africa and/or South Asia demonstrate differing rates of particular Y-DNA haplogroups.
R1b in Western Europe is dominated by at least two sub-clades, R-U106, ... while I2a is frequent also in Sardinia, Romania/Moldova, Bulgaria and Ukraine.
