They can be used to perform a rapid analysis, are very informative and are a standardized tool, which in turn facilitates the comparison of results between laboratories and their storage in databases of forensic interest. The main application of this type of marker is based on its capacity for individualization, i.e. to differentiate the genetic profile of two different people (except for monozygotic twins). This allows, for example, to determine the probability of a kinship relationship between two suspected relatives through the statistical evaluation of their genetic profiles, or to establish the probability that a suspect has contributed to the profile of the sample obtained at a crime scene.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/MPSforensic geneticsbiogeographic originmissing persons identification3203 Medicina forense241007 Genética humanadoctoral thesisopen access
