An unexpected case in the prehistory of the Iberian Peninsula: Biogeographical origin analysis through mitochondrial DNA

We have determined the mitochondrial haplotype (A73G T16172C C16223T G16257A C16261T) on a Bronze Age Individual from an archaeological site located in Alaejos (Valladolid, Central Spain).

Biological kinship analysis in extremely critical samples: the case of a Spanish Neolithic necropolis

This study aims to investigate the biological relationship among six Neolithic individuals (4200–3400 cal BC) from the Can Gambús-1 necropolis (Barcelona, Spain) as well as, their possible mitochondrial ancestry.

Updated mtDNA study of Guinea-Bissau immigrant population living in Lisbon

We studied 80 blood samples from Guinean immigrants living in Lisbon. mtDNA control region was amplified and sequenced between positions 16024 and 576, using two sets of primers - L15971/H016 and L16555/H639-.

Meta-Analysis of Mitochondrial DNA Variation in the Iberian Peninsula

In the present study we sequenced the control region of 3,024 Spanish individuals from areas where available data were still limited. We also compiled mtDNA haplotypes from the literature involving 4,588 sequences and 28 population groups or small regions.

An assessment of a massively parallel sequencing approach for the identification of individuals from mass graves of the Spanish Civil War (1936-1939)

Next generation sequencing technologies have opened new opportunities in forensic genetics. Here we assess the applicability and performance of the MiSeq FGx™ & ForenSeq™ DNA Signature Prep Kit (Illumina) to the identification of individuals from the mass graves of the Spanish Civil War (1936-1939).

The Expanded mtDNA Phylogeny of the Franco-Cantabrian Region Upholds the Pre-Neolithic Genetic Substrate of Basques

Recent data on complete mitochondrial DNA genomes focused on macrohaplogroup R0 revealed that Basques harbor some autochthonous lineages, suggesting a genetic continuity since pre-Neolithic times. However, excluding haplogroup H, the most representative lineage of macrohaplogroup R0, the majority of maternal lineages of this area remains virtually unexplored, so that further refinement of the mtDNA phylogeny based on analyses at the highest level of resolution is crucial for a better understanding of the European prehistory.

The relationship between surname frequency and Y chromosome variation in Spain

In most societies, surnames are passed down from fathers to sons, just like the Y chromosome. It follows that, theoretically, men sharing the same surnames would also be expected to share related Y chromosomes. Previous investigations have explored such relationships, but so far, the only detailed studies that have been conducted are on samples from the British Isles. In order to provide additional insights into the correlation between surnames and Y chromosomes, we focused on the Spanish population by analysing Y chromosomes from 2121 male volunteers representing 37 surnames.
