“…For example, haplotypes Y*(xDE, Q3) DYS389I(10) DYS391(10) and Y*(xDE, Q3) DYS389I(10) DYS391(11), which account for 66.7% in Tacuarembó (Table 3), are common in Europe. However, Tacuarembó show higher frequencies than in Spain, where they are up to 54.7% in the northwest (Brion et al, 2003) and 43.4% in the east (Jimenez et al, 2001).…”

“…DE* is not restricted to African populations and can be considered also to come from European ancestry (Hammer, 1994;Persichetti et al, 1992;Spurdle et al, 1994); in the Mediterranean region, its frequency is higher than the rest of Europe, with values as high as 27% in Sicily or 25% in Greece, and it gradually diminishes to the North of Europe (Cruciani et al, 2004;Semino et al, 2004). The haplotype DE* DYS389l(11) DYS391(9) is present in Spanish populations with a frequency that ranges from 2.5% to 8.0% (Brion et al, 2003;Jimenez et al, 2001), higher than the frequency we found, and it is present in the Maghreb population with a frequency of 25% (Brion et al, 2003). The haplotype DYS389l(11) DYS391(9) has the highest frequency in the Iberian peninsula (9%), and its frequency decreases to the North of Europe; in Africa, its frequency is highest in the Saharan populations, from 63% in Tunisian Arabs to 0.6% in Bantu speakers from South Africa (data taken from www.ystr.org).…”

The Uruguayan population has been considered as mainly European descent, with a negligible Native American or African contributions. Based on serological and molecular markers, recent studies demonstrate that these two populations had an important influence in the conformation of the present one. To the Northeastern region of Uruguay, a 20% Native American contribution was estimated using autosomal markers and a 62% Native American female origin based on mitochondrial markers. In this paper, we analyze four Y chromosome markers, two biallelic loci (M3 and YAP) and two microsatellites (DYS389I and DYS391), to characterize the male genetic contribution of a sample from the Northeastern city of Tacuarembó. We take different approaches to estimate the origin of male contributions to the population of Tacuarembó; Native American contribution ranges between 1.60% and 8.31%, confirming strong directional mating, which was also detected before with mitochondrial markers. Furthermore, the male population of Tacuarembó presents the characteristic of a population that suffered a bottleneck and a posterior expansion, confirmed using two microsatellite-based statistics to analyze the past population growth; patrilocality and migration could be responsible of those characteristics.

“…In order to evaluate the existence of genetic differentiation between Ibiza and other Balearic Islands, published data on two insular populations, Majorca and Minorca (Jiménez et al, 2001(Jiménez et al, , 2003, were included. AMOVA was used to assess the degree and significance of differentiation between islands.…”

We report on a comparison of the genetic diversity between Ibiza and the population of the other Balearic islands and also between the archipelago with respect to circum-Mediterranean populations. For such a comparison, autosomal and Y-chromosome STRs, as well as mtDNA sequence data analyzed from the same individuals, were studied. Analysis of 14 autosomal STRs showed that Ibiza had significant differentiation with respect to other Balearic populations and also with respect to insular and continental populations from the Mediterranean area. Nevertheless, the results obtained from the analysis of eight Y-STRs showed a high level of genetic homogeneity for eight western Mediterranean populations. On the other hand, these populations did not show a compacted group when mtDNA diversity was analyzed, since they showed genetic differentiation among them. The analyses of haplotypes shared between populations indicated that mtDNA haplotypes have drifted to higher frequencies than the Y chromosome. This fact could be due to a shared recent history between Ibiza and other western Mediterranean populations, with numerous male displacements originated by wars and, especially, commercial relations. The results of mtDNA from the Ibiza population could be due to a maternal Carthaginian/Phoenician founder effect, together with genetic drift, in accordance with the historical and demographic data of the area.

“…The presence of a strong genetic boundary between the northern and southern Mediterranean populations, especially in the western side of the sea has been suggested [3,8-10]. Studies focused on smaller areas have also given interesting results, especially those regarding physical and/or cultural isolates such as Corsican [11] and Sardinian sub-isolates [12], Balearic populations [13-15] and Calabrian populations [16]. …”

BackgroundDue to its history, with a high number of migration events, the Mediterranean basin represents a challenging area for population genetic studies. A large number of genetic studies have been carried out in the Mediterranean area using different markers but no consensus has been reached on the genetic landscape of the Mediterranean populations. In order to further investigate the genetics of the human Mediterranean populations, we typed 894 individuals from 11 Mediterranean populations with 25 single-nucleotide polymorphisms (SNPs) located on the X-chromosome.ResultsA high overall homogeneity was found among the Mediterranean populations except for the population from Morocco, which seemed to differ genetically from the rest of the populations in the Mediterranean area. A very low genetic distance was found between populations in the Middle East and most of the western part of the Mediterranean Sea.A higher migration rate in females versus males was observed by comparing data from X-chromosome, mt-DNA and Y-chromosome SNPs both in the Mediterranean and a wider geographic area.Multilocus association was observed among the 25 SNPs on the X-chromosome in the populations from Ibiza and Cosenza.ConclusionOur results support both the hypothesis of (1) a reduced impact of the Neolithic Wave and more recent migration movements in NW-Africa, and (2) the importance of the Strait of Gibraltar as a geographic barrier. In contrast, the high genetic homogeneity observed in the Mediterranean area could be interpreted as the result of the Neolithic wave caused by a large demic diffusion and/or more recent migration events. A differentiated contribution of males and females to the genetic landscape of the Mediterranean area was observed with a higher migration rate in females than in males. A certain level of background linkage disequilibrium in populations in Ibiza and Cosenza could be attributed to their demographic background.
