The Use of Y-Chromosome Profiles in Forensic Genetics

In forensic science, Y-STR testing is one of the most common tools used to interpret DNA typing results, specifically for human identification purposes (SWGDAM, 2014). With the complexity in DNA samples, not only can they be different from another individual, but each unique haplotype contains several markers with different combinations of alleles. While unique haplotypes do not arbitrate identity of individuals, methods in calculating numerical strength to a match between forensic evidence and a suspect remains an area of debate. This study used Y-STR profiles from worldwide databases to evaluate and explore the alleles shared within and between each population. It also raises some of the ethical considerations associated with the use of Y-STR profiles for forensic genetics purposes. If Y-STR typing or genetic profiling is the future of forensic genetics, more research needs to be done to ensure that the methods and technologies are effectively delivered and to assure public trust.
