Mitochondrial DNA control region sequence polymorphism in four indigenous tribes of Chotanagpur plateau, India

The analysis of genetic variation, in the nucleotide sequences of mitochondrial DNA, provides unique information in tracing of maternal lineage, determination of population diversity, pharmacogenomics and human identification. This study characterizes the HVR-I and II sequence polymorphism in 80 tribal individuals, belonging to the Austro-Asiatic linguistic family of Chotanagpur plateau, India. A total of 115 polymorphic sites were observed in the sequenced regions and 77 unique haplotypes could be identified.
