Haplotypes distribution

- Haplogroup A [4.76%] (suhaplogroup A2)
- Haplogroup B [2.38%]
- Haplogroup C [11.9%] (suhaplogroup C1)
- Haplogroup D [19.04%] (suhaplogroup D2)
- subahplogroup X6 [16.7%]
- subahplogroup X7 [9.5%]

- The presence of all four of the founding haplogrpoups identified by the Torroni group (and seven of Merriwether and Ferrell’s nine founding lineages), combined with Mongolia’s location with respect to the Bering Strait, indicates that Mongolia is a potential location for the origin of the founders of the New World.

- Since Haplogroup B, which is widely distributed in the New World, is absent in Siberia, Mongolia or a geographic location common to both contemporary Mongolians and American aboriginals is the more likely origin of the founders of the New World. (#8659526#)

DNA analysis of necropolis

- DNA was extracted from the skeletal remains of 62 specimens excavated from the Egyin Gol necropolis, in northern Mongolia. This burial site is linked to the Xiongnu period and was used from the 3rd century b.c. to the 2nd century a.d.

  • Close relationships have been found between several specimens and provided additional background information on the social organization within the necropolis as well as the funeral practices of the Xiongnu people.
