Population of Pedroches Valley, a hypothetical Berber settlement, located in the northwest portion of Córdoba province (Andalusia, Spain), had been analyzed for its Y‐chromosome diversity. Moreover, to contextualize this population, 127 Y‐chromosomes from a general Andalusia sample and a North African Berber community (Marrakech, Morocco) were also typed. For all samples, 24 single nucleotide polymorphisms of the non‐recombining portion of the Y‐chromosome (NRY) were analyzed and those samples… 
Micro and macro geographical analysis of Y-chromosome lineages in South Iberia.
Synthetic review on the genetic relatedness between North Africa and Arabia deduced from paternal lineage distributions
TLDR
Y-chromosome single-nucleotide polymorphisms in the Arab world are drawn to provide an anthropological approach to the analysis of the genetic landscape of these populations, showing an important paternal gene flow from the Middle East towards North Africa.
Mitochondrial DNA patterns in the Iberian Northern plateau: population dynamics and substructure of the Zamora province.
TLDR
The differences observed in the genetic pool of the sampled area at regional level results from the mixture of different populations carrying new lineages into this area at different points in history.
A revised root for the human Y chromosome differentiation and diversity landscape among North African populations
TLDR
With the maturation of sequencing and genotyping technologies, a tremendous increase in all kinds of genetic data looms, it is an appropriate time to reflect on what the Y chromosome can offer to population-genetic studies.
The history and geography of the Y chromosome SNPs in Europe: an update.
TLDR
The state of the art of the phylogenetic and phylogeographic research on Y chromosome SNP analyses in Europe is reported, updating the review published in this Journal by Francalacci & Sanna at the beginning of 2008.
Early Medieval Muslim Graves in France: First Archaeological, Anthropological and Palaeogenomic Evidence
TLDR
This study provides the first archaeo-anthropological testimony of the Muslim establishment in South of France through the multidisciplinary analysis of three graves excavated at Nimes, and proposes that the skeletons from the Nimes burials belonged to Berbers integrated into the Umayyad army during the Arab expansion in North Africa.
Molecular polymorphism of the ABO blood group: A study in Poland, Spain, and Andorra
The main goal of this study is to increase knowledge on the molecular level of the ABO blood group system in Europe by providing data for Poland, Spain, and Andorra populations.

Y‐chromosome Lineages from Portugal, Madeira and Açores Record Elements of Sephardim and Berber Ancestry
TLDR
The present composition of the Y chromosomes in Portugal in this haplogroup likely reflects a pre‐Arab component shared with North African populations or testifies, at least in part, to the influence of Sephardic Jews.
The African contribution to the present‐day population of the Azores Islands (Portugal): Analysis of the Y chromosome haplogroup E
TLDR
The present‐day representation of sub‐Saharan lineages in Azores, although reduced, is higher than in other Portuguese populations, where the demographic representation ofSub‐Saharan slaves is reported as similar.
A predominantly neolithic origin for Y-chromosomal DNA variation in North Africa.
TLDR
The Neolithic transition in this part of the world was accompanied by demic diffusion of Afro-Asiatic-speaking pastoralists from the Middle East, and it is suggested that the North African pattern of Y-chromosomal variation is largely of Neolithic origin.
Reduced genetic structure of the Iberian peninsula revealed by Y-chromosome analysis: implications for population demography
TLDR
The results indicate that neither old or recent Levantine expansions nor North African contacts have influenced the current Iberian Y-chromosome diversity so that geographical patterns can be identified.
High-resolution analysis of human Y-chromosome variation shows a sharp discontinuity and limited gene flow between northwestern Africa and the Iberian Peninsula.
TLDR
The most striking results are that contemporary NW African and Iberian populations were found to have originated from distinctly different patrilineages and that the Strait of Gibraltar seems to have acted as a strong (although not complete) barrier to gene flow.
Analysis of Y-chromosome variability and its comparison with mtDNA variability reveals different demographic histories between islands in the Azores Archipelago (Portugal).
TLDR
An assessment of the NRY variability, and its comparison with mitochondrial DNA (mtDNA) variability, was further evidence of the differential composition of males during the settlement of the three groups of islands, contrary to what has been previously deduced for the female settlers using mtDNA data.
Phylogeographic analysis of haplogroup E3b (E-M215) y chromosomes reveals multiple migratory events within and out of Africa.
TLDR
The present study shows that earlier work based on fewer Y-chromosome markers led to rather simple historical interpretations and highlights the fact that many population-genetic analyses are not robust to a poorly resolved phylogeny and reveals signatures of several distinct processes of migrations and/or recurrent gene flow that occurred in Africa and western Eurasia over the past 25000 years.
The place of the Basques in the European Y-chromosome diversity landscape
TLDR
It is found that at least some lineages of Y chromosome in modern Basques originated and have been evolving since pre-Neolithic times, and the strong genetic drift experienced by the Basques does not allow Basques either the only or the best representatives of the ancestral European gene pool.
The Y‐chromosome short tandem repeats variation within haplogroup E3b: Evidence of recurrent mutation in SNP
TLDR
The results show that the mutation rate for some SNPs could be higher than previously thought and also that it is important to associate both haplotype and haplogroup in Y‐chromosome studies.
Paternal and maternal lineages in the Balkans show a homogeneous landscape over linguistic barriers, except for the isolated Aromuns
TLDR
This work has sought to find any evidence of genetic stratification related to those cultural layers by typing both mtDNA and Y chromosomes, in Albanians, Romanians, Macedonians, Greeks, and five Aromun populations.
