ResumoMitochondrial DNA (mtDNA) lineages of 354 male samples from the five districts of Northern Portugal were defined. The aim was to obtain the female demographic history of this region and to compare it with the one obtained from Y chromosome haplotypes. The mtDNA landscape of North Portugal is in agreement with the one obtained from Y chromosome analysis, suggesting an East–West gradient in haplotype diversity. However, contrary to what happens with the Y chromosome, the easternmost district was the most diverse. Several explanations for this contrasting pattern are advanced.
