Skin colour in the Basque population

Skin colour has been analysed in 352 males and 393 females of the Basques. Measurements of upper-arm reflectance were taken using 9 filters of an EEL reflectance spectrophotometer. Regional differences are not found. Sexual dimorphism is not equally revealed in all filters in the same manner, but females are, on average, lighter skinned than males. By means of Penrose's size ans shape distance comparisons were made with several European populations.
