Haplogroup R1b (R-M343), previously known as Hg1 and Eu18, is a human Y-chromosome haplogroup.

2006年1月17日 · R1b3 is the most common Y haplogroup among men of European descent. Fourteen of the 30 most common haplotypes in the YSTR.org database are typical of R1b3. (Those haplotypes can be seen here).

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). [7]

With a 95% probability, the most recent common ancestor of all members of haplogroup 3615 1566 BCE. She is the ancestor of at least 2 descendant lineages known as R1b3a and 1 yet unnamed lineage. Descendant lineages are identified …

R1b is the most common haplogroup in Western Europe, reaching over 80% of the population in Ireland, the Scottish Highlands, western Wales, the Atlantic fringe of France, the Basque country and Catalonia. It is also common in Anatolia and around the Caucasus, in parts of Russia and in Central and South Asia.

2010年8月25日 · Here, we present phylogeographically resolved data for 2043 M269-derived Y-chromosomes from 118 West Asian and European populations assessed for the M412 SNP that largely separates the majority of Central and West European R1b lineages from those observed in Eastern Europe, the Circum-Uralic region, the Near East, the Caucasus and Pakistan.

2021年5月27日 · Haplogroup R1b (R-M343) is the most frequently occurring Y-chromosome haplogroup in Western Europe and the most common haplogroup in the genetic genealogy databases. R1b1a2 (R-M269) is the dominant branch of R1b in Western Europe.

The vast majority of Northern Europeans are R1b3, defined by marker M269+. The R1b haplotype (a set of marker scores indicative of the haplogroup) is very difficult to interpret because the R1b markers are found at relatively high frequency where the Anglo-Saxon and Danish invaders originally called home.

"The members of R1b3 (or R-M269, formerly known as R1b) are believed to be the descendants of the first modern humans who entered Europe about 35,000-40,000 years ago ( Aurignacian culture). Those R1b3 forebearers were the people who painted the beautiful art in the caves in Spain and France.

In human genetics, Haplogroup R1b is the most frequent Y-chromosome haplogroup in Western Europe. Its frequency is highest in Western Europe, especially in Atlantic Europe (and due to European emigration, in North America, South America, and Australia).
