A genetic population study of six Y chromosomal STRs in Central-West African immigrants in Spain and Southwest Spain populations

STRs on the Y chromosome are very useful for sex identification as well as for individual identification and paternity testing [1]. Likewise, these markers can be particularly helpful to detect male DNA fractions in stains involving male/female mixtures, the most common biological material found in sexual crimes [2]. In the present study, the allele distributions of the polymorphic loci DYS19, DYS385, DYS389I, DYS389II, DYS390 and DYS393 were examined in Southwest Spain and the black West African immigrant population.
