Y-DNA Haplogroup R is perhaps the most prominent Y-DNA lineage on Earth today. It is the pre-eminent Y haplogroup in Europe, the U.S. and India. While the exact location for the origin of Haplogroup R is under debate, its general placement in West-Central Asia was followed by expansion in all directions, stretching to the ‘Seven Seas’. The date for its origin is in the Paleolithic Era, 35-40kya, and populations harboring this Y-DNA variant survived the Ice Ages to repopulate much of Europe and Asia. Migration episodes included excursions to Africa, South East Asia and in recent eras, the invasion of and immigration to the Americas by West European nations such as Spain, England and Ireland where the levels of Haplogroup R are near 90%. The Atlantic Modal Haplotype, a popular haplotype on both sides of the Atlantic Ocean, is also linked to Y-DNA Haplogroup R.
The further refinement of Y-DNA ancestry can be obtained by using the Y-DNA Haplogroup R Subclade Testing Panel from Genebase. This panel is based upon a collection of SNPs that identify sub-branches or subclades of Y-DNA haplogroup R. This haplogroup has many subclades, most stemming from the R1b branch of the tree.
If you are a confirmed member of Y-DNA Haplogroup R, dig further using the Y-DNA R Subclade SNP Test and find out which Subclade of R you descended from.
