| Abstract: | In recent years, autosomal single nucleotide polymorphisms (SNPs) have been comprehensively investigated in forensic research due to their usefulness in certain circumstances in complementing short tandem repeats (STRs) analysis, or even for use on their own when analysis of STRs fails. However, as with STRs, in order to properly use SNP markers in forensic casuistic we need to understand the population and forensic parameters in question. As a result of Portugal’s colonial history during the time of empire, and the subsequent process of decolonization, some African individuals migrated to Portugal, giving rise to large African and African-descendent communities. One of these groups is the community originating from Guinea-Bissau, that in 2014, was enumerated to consist of more than 17,700 individuals with official residency status, more than the third major city of Guinea-Bissau.In order to study the population and forensic parameters mentioned above for the two populations important to our casuistic, a total of 142 unrelated individuals from the South of Portugal and 90 immigrants from Guinea-Bissau (equally non related and all residing in Portugal) were typed with SNaPshot? assay for all 52 loci included in the SNPforID 52plex. |
