Question: My friend did a geneology test,what does it mean when he has Haplogroup: B2 what ancestry must he have!?
Best Answer - Chosen by Asker:

This depends, is this y-dna or mtdna!?

In Y-DNA, B2 is based in sub-saharan Africa!. DNA generally spreads out quite far from the central location and I expect that there are tapering chances of coming from northern africa, middle east, Europe, etc!.

mtDNA, sounds native American!.

Technically, this only represents that one line!.!.!. The rest of the DNA being the same is based only on the normal chance of correlation that the rest of the DNA is related!. i!.e!. that if one line is such and such, others were too!.Www@QuestionHome@Com

In mitochondrial genetics, Haplogroup B is a human mitochondrial DNA (mtDNA) haplogroup!.

Haplogroup B is believed to have arisen in Asia some 50,000 years before present!. Its ancestral haplogroup was Haplogroup R!.

Haplogroup B is found more often in East Asia[1]!. Its subgroup B2 is one of five haplogroups found in the indigenous peoples of the Americas, the others being A, C, D, and X!.

Since the migration to the Americas by the ancestors of Native Americans is generally believed to have been from Siberia, it is especially surprising that Haplogroup B is the only haplogroup found in Native Americans which is not found in modern North Siberian populations!. However, Haplogroup B has been found among Southern Siberians, such as Tuvans, Altays, and Buryats!. This haplogroup is also found in Mongolians, Tibetans, Koreans, and among populations of Japan, China, Taiwan, Indonesia, Madagascar, The Philippines, Polynesia and Micronesia!.

In his popular book The Seven Daughters of Eve, Bryan Sykes named the originator of this mtDNA haplogroup Ina!.Www@QuestionHome@Com

Haplogroup B2 is a Native American mtDNA Haplogroup!.
(on his mother's, maternal lineage)

The phylogenies of haplogroups A2, B2, C1, and D1 reveal a large number of sub-haplogroups but suggest that the ancestral Beringian population(s) contributed only six (successful) founder haplotypes to these haplogroups!. The derived clades are overall starlike with coalescence times ranging from 18,000 to 21,000 years

No, it means that his mother, or the lineage of one of his maternal grandmother's has Native American in it, so obviously he has some NA genes, but I doubt that he can be called "Indian"!. His own Y-Dna haplogroup, that of his male lineage, more precisely shows his origins!.Www@QuestionHome@Com
