G-P15 (Y-DNA)

This project is for people who have tested and been assigned the paternal haplogroup G (P15) and also for people who are believed to have belonged to this paternal haplogroup based on tests done on descendants.

Defining Mutations

• P15

G2a men will be positive for other genetic markers:

• G (M201), about 17,000 years ago
• G2 (P287), about 15,000 years ago
• G2a (P15), about 15,000 years ago

(Haplogroup G Categories; Haplogroup G Origins & Dating.)

Origin

The origin of haplogroup G is controversial. The most recent study (2010) estimates the common ancestor of all men in haplogroup G lived in Asia about 17,000 years ago, and the ancestor of the G2 subgroup lived about 15,000 years ago.

Distribution

Men with the haplogroup G marker moved into Europe in Neolithic times. It is one of the least common haplogroups in Europe. Haplogroup G2a might have been the main Neolithic link that ties the farmers that went north across the Balkans to Central Europe, and those that followed the western, maritime route to the Western Mediterranean. See Dienekes Anthropology Blog, Y-chromosome, mtDNA, and autosomal DNA from Treilles (5,000 years ago, Neolithic France).

The oldest skeleton confirmed by DNA testing as carrying haplogroup G was found at the Neolithic cemetery of Derenburg Meerenstieg II in north central Germany. Burial artifacts in the cemetery belong to the Linear Pottery culture. This skeleton could not be dated by radiocarbon dating, but other skeletons there were dated to between 5,100 and 6,100 years old. This skeleton's DNA was found to belong to subgroup G2a3.

Update October 15, 2010: The presumptive haplogroup of Louis XVI was G2a, the same as 2 of 5 warriors from Merovingian Bavaria (7th c. AD). See Dienekes Anthropology Blog, Y chromosome and mtDNA of Louis XVI of France. This family is likely to be G2a3b1a6 - DYS643=9. See Haplogroups of European kings and queens.

Update September 15, 2011: The DNA of Otzi the Iceman, a Neolithic skeleton found in the Tyrolean Alps has been sequenced. He belonged to G-L91. See Dienekes Anthropology Blog, Ötzi, the Tyrolean Iceman belonged to Y-haplogroup G2a4. (G2a4 was later renamed G2a2b.)

Update October 9, 2013: Using DNA samples from three living members of the House of Bourbon, a new study shows the family belonged to R-Z381* (a subgroup of R-106), not G2a. See Dienekes Anthropology Blog, House of Bourbon belonged to Y-haplogroup R1b1b2a1a1b* (R-Z381*), Oct. 9, 2013.
