Abstract

The polymorphisms of mitochondrial DNA for the restriction enzymes HpaI, BamHI, HaeII, MspI, AvaII and HincII were studied in a sample of 79 Hindus, 45 from New Delhi (India) and 34 from Terai (Nepal), both to characterize another Caucasian population and to investigate some possible Hindu component in the genetic structure of the Tharus, a Nepalese population, the anthropological position of which is still disputed. 1. A new BamHI polymorphism was detected; about 5% of the Hindu mtDNAs have lost the site at 14258 bp and lack any BamHI site. Once again a BamHI polymorphism was found in a Caucasian population. 2. New site mutations were found to yield morphs previously described (MspI-7, AvaII-18). 3. Variant morphs for two different enzymes were found due to a shared mutation (morphs BamHI-0/AvaII-30 and morphs MspI-7(Hindu)/AvaII-18(Hindu)) 4. Comparison between Hindu and Tharu data does not show any evidence of a specific Indian component in the Tharu genetic structure and allows us to conclude that Tharus are clearly differentiated from modern Hindus.
