Resumen: DNA samples of hundred ten unrelated anonymized male individuals living in province of Entre Rios, Argentina, were genotyped using Investigador Argus X-12 system (Qiagen) for 12 STRs in four haplogroups. 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.
