Genetic study of 15 STRs loci of Identifiler system in Angola population.

Angola is located in the African continent, in the area of southern Africa and has a population of approximately 14 million inhabitants. The Angola population has origin from Occidental and Southern Bantu people that came from the great lakes region, creating the most ever known African migration of our days. Allele frequencies for the 15 STRs loci in the AmpFlSTR Identifiler kit (D8S1179, D21S11, D7S820, CSF1PO, D3S1358, HUMTH01, D13S317, D16S539, D2S1338, D19S433, HUMVWA, TPOX, D18S51, D5S818, HUMFIBRA/FGA and including the segment of the X-Y homologous gene amelogenin) were studied for Angola population.

Distribution of Y-chromosomal haplotypes in the Central Portuguese population using 17-STRs.

17 Y-chromosome STR loci (DYS19, DYS389I, DYS389II, DYS390, DYS456, DYS391, DYS392, DYS393, DYS385 a/b, DYS458, DYS439, DYS635, GATA H4.1, DYS437, DYS438 and DYS448) were determined for 303 unrelated males, living in Central Portugal, using the AmpFlSTR YFiler PCR Amplification kit (Applied Biosystems). A total of 287 different haplotypes were found, 272 being unique.

Allelic frequency distribution of 17 STRs from Identifiler and PowerPlex-16 in Central Portugal area and the Azores archipelago.

This study analyzes the allelic frequency distribution of 17 STRs contained in the AmpFlSTR Identifiler (Applied Biosystems) and PowerPlex16 System (Promega) commercial kits for two large population samples from the Azores archipelago (Portugal) (N=475) and from Central Portugal (N=2125). Likewise, it includes a comparative study among the population groups analyzed in this paper and those which history points out as originating from the first settlers of the Azores. All loci were highly polymorphic.

A study of Spanish attitudes regarding the custody and use of forensic DNA databases.

One of the issues that has resulted in much disagreement in many countries at different levels concerns the kind of institution that should be given the responsibility of exercising custody over biological samples and the DNA profiles obtained from these samples. In the field of forensic genetics, there is no doubt that the existence of DNA criminal databases benefits the control and investigation of crime. However, certain criticism, supported to a great extent by the particular vision of genetic exceptionalism has been aimed at the ethical and social consequences resulting from the inappropriate use of such databases.

Y-chromosome STR haplotypes in two population samples: Azores Islands and Central Portugal.

The Y-chromosome haplotypes defined by nine STRs (DYS19, DYS385, DYS389I, DYS389II, DYS390, DYS391, DYS392 and DYS393) were studied in 207 unrelated individuals from Central Portugal and 63 from Azores Islands. The most common haplotype in Central Portugal was shared by 3.4% of the males, while 160 haplotypes were unique.

Y-chromosome STR haplotypes in a southwest Spain population sample.

The Y-chromosome polymorphism of eight STRs (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392; DYS393, DYS385) were studied in 111 unrelated individuals from the population of southwest Spain. The most common haplotype was shared by 3.6% of the sample, while 99 haplotypes were unique.
