“…Cinnioğlu et al () initially reported M365.1 in one Turkish individual (out of 523 males examined), though showing a different Y‐STR minimal haplotype, DYS19‐15/DYS389I‐13/DYS389II‐28/DYS390‐22/DYS391‐10/DYS392‐11/DYS393‐14, and Semino et al () detected it in two Turks and one Georgian (out of >2400 subjects). The Y‐STR minimal haplotype (plus DYS385a/b‐12,20) from the J1a1‐M365.1 male here identified was also previously reported in one sample from northern Portugal (Sánchez‐Diz et al, ) as well as in one sample from Brazil (Pereira, Monteiro, Hirschfeld, Wang, & Grattapaglia, ). Moreover, in the Y‐STR Haplotype Reference Database (YHRD) (https://yhrd.org/search/search), this Y‐STR minimal haplotype matched one sample from Iran (Caspian sea; one match in 984 haplotypes), whereas its one‐step neighbor bearing DYS385a/b‐12, 19 presented two matches in 1884 haplotypes from Portugal, four matches in 8007 from Brazil, one match in 3349 from Mexico and one match in 2185 from Turkey.…”

While previous inferences based on modern haplogroup J Y-chromosomes implicated a main Neolithic dissemination, here we propose a later arrival of J lineages into Iberia using a combination of novel Portuguese Y-chromosomal data and recent evidence from ancient DNA. Our analysis suggests that a substantial tranche of J1-M267 lineages was likely carried into the Iberian Peninsula as a consequence of the trans-Mediterranean contacts during the first millennium BC, while most of the J2-M172 lineages may be associated with post-Neolithic population movements within Europe.

“…The overallĤ = 0.992±0.001 is lower than reported in other populations as well. For the sake of comparison, analyses of 250 males from Portugal [1] and 500 males from Brazil [18] have recently reported Yfiler haplotype diversitiesĤ >0.999. The highest absolute haplotype frequency in both of these studies was 3, corresponding to 1.2% and 0.6% in the Portuguese and Brazilian samples, respectively.…”

The effect of number of loci on geographical structuring and forensic applicability of Y-STR data in Finland

The Y-chromosomal diversity among Finnish males is characterized by low diversity and substantial geographical substructuring. In a 12-locus data set (PowerPlexY), especially the eastern parts of the country showed low levels of variation, and the western, middle, and eastern parts of Finland differed from each other by their Y-short tandem repeat (STR) haplotype frequencies (Palo et al., Forensic Sci Int Genet 1:120-124, 2007). In this paper, we have analyzed geographical patterns of Y-STR diversity using both 12-locus (PowerPlexY) and 17-locus (Yfiler) data sets from the same set of geographically structured samples. In the larger data set, the haplotype diversity is significantly higher, as expected. The geographical distribution of haplotypes is similar in both data sets, but the level of interregional differences is significantly lower in the Yfiler data. The implications of these observations on the forensic casework are discussed.

“…Brazilian genetic data on autosomal [8,9] and Ychromosome STRs [10][11][12] are already available, but few studies have been published regarding the X-STRs in Brazil [5,7,[13][14][15][16]. Thus, the aim of the current study was to analyze the 10 X-STRs standardized by the GHEP-ISFG [7] in capital cities of the southeastern region of Brazil (São Paulo, Rio de Janeiro, Vitória and Belo Horizonte).…”

Ten X-chromosomal short tandem repeats (DXS8378, DXS9902, DXS7132, DXS9898, DXS6809, DXS6789, DXS7133, GATA172D05, GATA31E08 and DXS7423) were analyzed in four populations of the southeastern region of Brazil (São Paulo, Rio de Janeiro, Vitória and Belo Horizonte). No deviations from the Hardy-Weinberg equilibrium were observed for any of the analyzed loci in the four populations. The average diversity per locus varied between 68% for DXS8378, DXS7133, and DXS7423 and 83%, for DXS6809, with Rio de Janeiro being the most diverse population. Overall power of discrimination values in females varied between 0.99999999990 and 0.99999999997 and between 0.9999991 and 0.9999995 in males. These high values show the potential of this system for forensic application and relationships' testing in the studied groups. Genetic comparisons (exact tests of population differentiation and pairwise genetic distances) revealed significant differences between Brazilian and other populations from Europe, Latin America and Africa, as well as among different Brazilian populations.
