During the study of genetic diversity at non-core Y STRs in South African population groups, the authors identified loci with high discrimination capacity. This study presented a detailed account of the allele diversity, allele sequence data, gene diversity, allele frequency spectrum, and informativeness for assignment in the European English, Asian Indian, and Xhosa population groups at loci DYS449, DYS481, DYS518, DYS612, DYS626, DYS644, and DYS710. The suitability of these loci for forensic, genealogical, and evolutionary studies is discussed, and nomenclature for loci DYS518, DYS612, DYS626, and DYS644 is suggested.
