An analysis of 15 autosomal short tandem repeat (STR) loci and 17 Y-STR loci was performed in 123 unrelated members of the Oraon tribal community of Central India. The combined power of discrimination (CPD) and combined power of exclusion (CPE) were greater than 0.99999 and 0.999989, respectively, for autosomal STRs. In addition, a total of 58 distinct Y-STR haplotypes were observed out of which 54 Y-STR haplotypes were observed only once. The haplotype diversity and discrimination capacity for 17 Y-STR loci was 0.997 and 0.906, respectively.

Keywords: Autosomal STR; Forensic; Oraon; Population data; Y-STR.
