Abstract 

Commercial Y-STR kits have permitted laboratories to go beyond the original nine minimal haplotype loci (MHL) and to discover the advantage of additional Y-STR loci in resolving common haplotypes. In an effort to examine the impact of Y-STR markers beyond the 17 loci now available in commercial kit form, new Y-STR loci are being investigated on a common set of samples representative of the major U.S. population groups. Additional Y-STRs can also increase the power of discrimination between closely related male individuals, which is important not only in forensics but also in the paternity and genetic genealogy communities.
