Summary

Skin colour has been studied in a Biscayan sample of males and females, not related, between 8 and 19 years of age. Data, collected by reflectometry, have been used to quantify the degree of interpopulation heterogeneity for skin colour on the Biscayan Coast through the implementation of r I and r O . The spectral region that measures the melanine quantity better seems to afford the greater part of the heterogeneity found. Mean values of heterogeneity are bigger in females than in males. Sopelana, Múgica and Lequeitio samples appear to have received a greater amount of gen flow with respect to the expected values when reflectance data are used in the extended model of Harpending and Ward (1982) for quantitative traits.
