The frequency of most common haplotype was 0.02727, 0.06364, 0.03636, and 0.03636 for haplogroups 1, 2, 3, and 4, respectively. The Match Probability was 6.0E-08 and the mean exclusion chance was 0.999999936. This work presents the first haplotype frequency data for Investigator Argus X-12 system in a population of Argentina.2015http://zaguan.unizar.es/record/10964410.1016/j.fsigss.2015.09.207http://zaguan.unizar.es/record/109644oai:zaguan.unizar.es:109644Forensic Science International: Genetics Supplement Series 5 (2015), e524-e526All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/openAccess
