Abstract
Genetic data from 17 autosomal short tandem repeat (STR) loci found in the Powerplex® ESX 17 System (Promega, Madison, WI, USA) was evaluated in 162 unrelated Mexican Mestizo individuals from Mexico City. Allele frequencies and forensic parameters were estimated for the 17 STRs. All loci analyzed were in Hardy-Weinberg equilibrium in the studied population and showed not any signs of linkage between loci. The combined power of discrimination and the power of exclusion for the 16 aSTRs studied were 1–2.56409·10−19 and 99.999938 %, respectively. Genetic distances reveal a close relationship within different populations of Mexican Mestizos. The obtained data might be useful for population genetics research and for individual identification and paternity testing in forensic science.
