Other Y-DNA haplogroups reaching considerable frequencies among the Burusho are haplogroup J2, associated with the spread of agriculture in, and from, the neolithic Near East,[1][2] and haplogroup C3, of Siberian origin and possibly representing the patrilineage of Genghis Khan. Present at lower frequency are haplogroups O3, an East Eurasian lineage, and Q, P, F, and G.[27] DNA research groups the male ancestry of some of the Hunza inhabitants with speakers of Pamir languages and other mountain communities of various ethnicities, due primarily to the M124 marker (defining Y-DNA haplogroup R2a), which is present at high frequency in these populations.[31] However, they have also an East Asian genetic contribution, suggesting that at least some of their ancestry originates north of the Himalayas.[32] No Greek genetic component among the Burusho have been detected in tests.[33][34]
