Comparative Study of 10 X-STR Markers in Populations of Northeast Argentina

In northeast Argentina, different Amerindian communities share territory and history with settlers, mainly Europeans. Due to miscegenation, the current Argentinean population has a particular structure that can be described through X chromosome variation. The objectives of this study were describe variation 10 X-chromosome short tandem repeats (X-STRs) in urban populations regions known as Gran Chaco Mesopotamia, report forensic parameters these STRs, estimate European indigenous genetic components regions. Population estimated for 419 individuals from analyzed populations, including two groups, Wichí Mocoví, previously reported. was FST RST distances analysis molecular variance. American assessed STRUCTURE. X-STRs showed high level variability populations. Indigenous people region significant differentiation samples (FST = 5.5%) among themselves 5.3%). Genetic groups almost negligible, except Misión Nueva Pompeya differed rest city Forensic indicate are useful complement paternity tests. set STRs could good tool examining diffferences.
