The Eastern side of the Westernmost Europeans: Insights from subclades within Y‐chromosome haplogroup J‐M304
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 firs…

Y chromosome diversity in a linguistic isolate (Mirandese, NE Portugal)
OBJECTIVES: The purpose of this study was to genetically characterize the male lineages of people who speak Mirandese, an interesting case of a linguistic relict that can still be found in the municipality of Miranda do Douro, NE Portugal. This region lies within the area of the Leonese dialects, which are remnants of the Romance dialects spoken in the Kingdom of Leon currently grouped in the Astur-Leonese linguistic continuum. We intended to dis…

Mirandese language and genetic differentiation in Iberia: A study using X chromosome markers
The results showed that Miranda do Douro tended to present slightly lower levels of diversity in comparison to the other studied regions, which can be a discreet sign of isolation of that population over the years that might have led the way to the preservation of a language not spoken anywhere else in the country. The analysis of X-STRs particularly brought to light the presence of a subtle population sub-structure at the micro-geographical area…
Colombia’s racial crucible: Y chromosome evidence from six admixed communities in the Department of Bolivar

Opening the DNA black box: Demythologizing forensic genetics
Social impact is intrinsic to any applied branch of genetics. Since the goal of forensic genetics is to provide expertise in legal disputes, the expert should make her- or himself understood. The urgent need for measures to deepen the communication between experts and non-experts requires debunking of some myths surrounding forensic genetics, and to (re)center the discussion on the solid ground of formal genetics. “Classical” forensic sciences re…
Refining the genetic portrait of Portuguese Roma through X‐chromosomal markers
Due to differences in transmission between X‐chromosomal and autosomal DNA, the comparison of data derived from both markers allows deeper insight into the forces that shape the patterns of genetic diversity in populations. In this study, we applied this comparative approach to a sample of Portuguese Roma (Gypsies) by analyzing 43 X‐chromosomal markers and 53 autosomal markers. Portuguese individuals of non‐Gypsy ancestry were also studied. Compa…

Male lineages in South American native groups: Evidence of M19 traveling south
With this study, we aimed to determine the different male ancestral components of two Native American communities from Argentina, namely Toba and Colla. The analysis of 27 Y‐chromosome SNPs allowed us to identify seven different haplogroups in both samples. Chromosomes carrying the M3 mutation, which typically defines the Native American haplogroup Q1a3a, were seen most frequently in the Toba community (90%). Conversely, Q1a3a was represented in …
Genetic profiling of the Azores Islands (Portugal): Data from 10 X‐chromosome STRs
The populations from the Azores islands have been the target of several genetic studies, using data derived from monoparental and recombining genetic systems. These studies have provided a complex picture of the genetic landscape of the three groups of Azorean islands, and further data are required to assess its genetic profile. We present a study of the polymorphism in 10 X‐chromosome STR loci (DSXS8378, DXS9898, DXS7133, GATA31E08, GATA172D05, …
Female Gene Pools of Berber and Arab Neighboring Communities in Central Tunisia: Microstructure of mtDNA Variation in North Africa
North African populations are considered genetically closer to Eurasians than to sub-Saharans. However, they display a considerably high mtDNA heterogeneity among them, namely in the frequencies of the U6, East African, and sub-Saharan haplogroups. In this study, we describe and compare the female gene pools of two neighboring Tunisian populations, Kesra (Berber) and Zriba (non-Berber), which have contrasting historical backgrounds. Both populati…
Post‐last glacial maximum expansion from Iberia to North Africa revealed by fine characterization of mtDNA H haplogroup in Tunisia
The first large‐scale fine characterization of Tunisian H lineages clarifies that the post‐Last glacial maximum expansion originating in Iberia not only led to the resettlement of Europe but also of North Africa. We found that 46% of 81 Tunisian H lineages subscreened for 1,580 bp in mtDNA coding region were affiliated with H1 and H3 subhaplogroups, which are known to have originated in Iberia. Although no signs of local expansion were detected, …
African Female Heritage in Iberia: A Reassessment of mtDNA Lineage Distribution in Present Times
The Iberian peninsula is a peripheral region of Europe in close proximity to Africa. Its inhabitants have an overall mtDNA genetic landscape typical of European background, although with signs of some African influence, whose features we deemed to disclose by analyzing available mtDNA HVRI distributions and new data. We analyzed 1,045 sequences. The most relevant results are the following: (1) North African sequences (haplogroup U6) present an ov…
Phylogeographic analysis of paternal lineages in NE Portuguese Jewish communities
The establishment of Jewish communities in the territory of contemporary Portugal is archaeologically documented since the 3rd century CE, but their settlement in Trás‐os‐Montes (NE Portugal) has not been proved before the 12th century. The Decree of Expulsion followed by the establishment of the Inquisition, both around the beginning of the 16th century, accounted for a significant exodus, as well as the establishment of crypto‐Jewish communitie…
Substructure of a Tunisian Berber Population as Inferred from 15 Autosomal Short Tandem Repeat Loci
Currently, language and cultural practices are the only criteria to distinguish between Berber autochthonous Tunisian populations. To evaluate these populations' possible genetic structure and differentiation, we have analyzed 15 autosomal short tandem repeat loci (CSF1PO, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D21S11, FGA, TH01, TPOX, VWA, D2S1338, and D19S433) in three southern Tunisian Berber groups: Sened, Matmata, and Ch…

Islands Inside an Island: Reproductive Isolates on Jerba Island
Jerba Island, located in South Eastern Tunisia, is inhabited by four ethnic groups: Berbers, Arabs, sub‐Saharans, and Jews. All live in distinct areas, although the Arabs are also distributed all over the island. The first Arab settlement was founded in the 7th century A.D., so co‐existence with Berbers has lasted for more than a millennium. Religious and cultural differences have represented an obstacle to the intermixing of these groups, and am…
Y‐STR haplotype diversity in distinct linguistic groups from East Timor
East Timor is a country which harbors multiple ethnolinguistic groups generally assigned to an Austronesian or Papuan ancestry. The present study aimed to characterize Y‐chromosome haplotype diversity in East Timor, and to test possible population structures based on linguistic and/or geographical information. Using a set of 12 Y‐chromosome‐specific STRs (DYS19, DYS389I and II, DYS390, DYS391, DYS392, DYS393, DYS385, DYS437, DYS438, and DYS439), …
Y-chromosome genetic variation in Rio De Janeiro population
The present-day Brazilian gene pool is known to be the outcome of an admixture process of populations from different origins, mainly Amerindians, Europeans, and Africans. It is also known that in Brazil, a wide variation in the admixture process occurred in different regions of the country or even in different subpopulations from the same region. In the present study, we aimed to characterize the male lineages present in the Rio de Janeiro popula…
Analysis of TPI gene promoter variation in three sub‐Saharan Africa population samples
Population samples from Angola, Mozambique, and S. Tomé e Príncipe were screened for the TPI gene promoter variants -5A-->G, -8G-->A and -24T-->G. Three haplotypes were identified in the three populations: the haplotype -5A-8G-24T (average frequency 65.3%) and two less common haplotypes -5G-8G-24T (average frequency 24.7%) and -5G-8A-24T (average frequency 10.0%). A population sample from Central Portugal showed the haplotype -5A-8G-24T in 139 ch…

Genetic characterization of uniparental lineages in populations from Southwest Iberia with past malaria endemicity
Malaria endemicity in Southwest Iberia afforded conditions for an increase of sickle cell disease (SCD), which in the region follows a clinal pattern toward the south, where foci of high prevalence were found. SCD distribution is associated with specific geographical areas, and therefore, its introduction into Iberia may be related to the migration of different populations. We have analyzed the variation of uniparental markers in Portuguese popul…
