Abstract

In this study 17 Y-chromosomal STRs (including DYS19, DYS389I, DS389II, DYS390, DYS391, DYS392, DYS393, DYS385a/b, DYS437, DYS438, DYS439, DYS448, DYS456, DYS458, DYS635 and Y GATA H4) were analysed using blood samples of 122 unrelated male individuals belonging to Saraswat Brahmin community from Jammu (ID YP000599) and Kashmir (ID YP000600) region of J&K state of India. The allelic frequency distribution and haplotype diversity of 17 Y-chromosomal STR for both the populations were calculated. In the Kashmiri Saraswat group, a total of 109 haplotypes were identified in 122 individuals, of these haplotypes, 101 were found only once. The gene diversity values of STR loci ranged from 0.4813 (DYS391) to 0.8645 (DYS385a/b) for Jammu & Kashmiri Saraswat Brahmins.
