Allele frequencies and forensic parameters were estimated for 11 X chromosome STRs (DXS9898, DXS7424, DXS981, DXS8377, DXS9895, DXS10161, DXS10164, DXS6800, DXS6801, DXS9902 and DXS7423) from 749 samples of unrelated male individuals belonging to eleven populations of India.

The human amelogenin gene resides on homologous regions of the sex chromosomes. However, a deletion in the AmelY locus may sometimes lead to gender misidentification.

Seventeen short tandem repeats (DYS389I, DYS390, DYS389II, DYS19, DYS385a/b, DYS393, DYS391, DYS392, DYS439, DYS438, DYS456, DYS458, DYS635, Y(GATA)H4, DYS437, and DYS448) from the non-recombining region of the human Y-chromosome were analyzed in 750 unrelated males representing four major linguistic families of India using AmpFlSTR(®) Yfiler(®) PCR Amplification kit. A total of 612 distinct haplotypes were observed, of which 545 were unique. Rare alleles for the loci DYS456, DYS458, DYS635, Y(GATA)H4, and duplication at the loci DYS389I and DYS389II were also observed.

In the present study, a decaplex for the co-amplification of ten X chromosomal microsatellite loci (DXS6807, DXS8378, DXS7132, DXS6809, DXS6789, DXS101, DXS7133, GATA172D05, HPRTB, and GATA31E08) was optimized and 749 blood samples of unrelated male individuals from the four major linguistic families of India were analyzed. The number of alleles for the studied loci ranged from 7-16 while the gene diversity values varied from 0.
