Positioning of the autochthonous Aran Valley population among Basque and Pyrenean people by means of ABO, Rh(D) and duffy blood group determinations

A total of 205 unrelated autochthonous individuals of both sexes from the population of the Aran Valley in the central Pyrenees were tested for ABO, Rh and duffy blood groups. This population is of interest because of its relative geographical and historical isolation and its specific peculiarities, such as its own language. The results show a good correlation between the principal component analysis graphic and the geographic positions of the Basque and Pyrenean populations with which the Aranese population is compared.
