A genetic marker is defined as a specific gene or DNA sequence that produces a detectable trait with a known location on a chromosome and that can be used to study family and population, identification of cells, species or individual. Introduction:
Ancestry informative markers or AIMs are defined as polymorphic loci with higher-than-average allele frequency differences between population groups. Forensic DNA testing can use the information obtained from AIMs to make an inference of the geographic origin, more correctly, the genetic ancestry of an individual.
