Abstract:
In the present study, allele frequencies and forensic parameters of four ethnic groups (Brahmin, Khatri, Jat Sikh, and Scheduled Caste) of Punjab, India, at 10 Alu insertions of X chromosome were calculated. Six Alu markers were observed to be highly polymorphic with no significant deviations from Hardy-Weinberg equilibrium and no linkage disequilibrium present in any marker. Multidimensional plot showed higher genetic affinity of studied populations with Asian populations. Overall, the tested markers were reliable and were found suitable in human forensics and population genetic studies.
