The black legend on the Spanish presence in the low countries: Verifying shared beliefs on genetic ancestry

War atrocities committed by the Spanish army in the Low Countries during the 16th century are so ingrained in the collective memory of Belgian and Dutch societies that they generally assume a signature of this history to be present in their genetic ancestry. Historians claim this assumption is a consequence of the so-called “Black Legend” and...

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.

Analysis of the R1b-DF27 haplogroup shows that a large fraction of Iberian Y-chromosome lineages originated recently in situ

Haplogroup R1b-M269 comprises most Western European Y chromosomes; of its main branches, R1b-DF27 is by far the least known, and it appears to be highly prevalent only in Iberia.

Micro and Macro Geographical Analysis of Y-Chromosome Lineages in South Iberia

To obtain a more comprehensive picture of the genetic structure of the South Iberian region as a whole, our data were compared with published data on neighboring populations. Our analyses allow us to confirm the specific impact of the Arab and Berber expansion and dominion of the Peninsula...

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 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.
