Studies the allele frequencies of different loci in a population in Central Spain. Extraction of DNA; Amplification of DNA; Separation of the amplified products; Classification of the alleles.

Haplotype, allele frequencies and population data of 17 Y-chromosome STR loci DYS19, DYS385, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439, DYS460 (GATA A7.1), DYS461 (GATA A7.2), GATA A10, GATA C4 and GATA H4 were determined from a sample of 148 unrelated male individuals from Spain. A total of 144 haplotypes were identified by the 17 Y-STR markers, of which 141 were unique, two were found in two individuals and one was found in three individuals. The haplotype diversity (99.95%) and discrimination capacity (97.30%) were calculated.Comparisons were made with previously published haplotype data on other Iberian population samples and no significant differences were found.

Abstract: Blood samples from 204 unrelated Basque Country autochthonous individuals were typed and their allele frequencies were determined. Results demonstrate the assumption of independence within and between the loci analyzed. Therefore, a Basque population database can be used in identity testing to estimate the frequency of a multiple PCR-based locus DNA profile. [Copyright &y& Elsevier]

Abstract: Haplotype, allele frequencies and population data of 17 Y-chromosome STR loci DYS19, DYS385, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439, DYS448, DYS456, DYS458, DYS635 (Y GATA C4) and Y GATA H4 were determined from a sample of 168 unrelated male individuals from the Basque Country. Individuals were considered autochthonous if the 8 surnames and birthplace of their grandparents were of Basque origin. The haplotype diversity (99.03%) and discrimination capacity (82.14%) were calculated. The combined polymorphism provides a powerful discrimination tool for routine forensic applications.
