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.

Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...
