Summary
Skin pigmentation has been analyzed by reflectometry in a biological sibling sample of the Biscay Province, whose ages ranged between 4+ - 20+ years, with the aim of estimating the degree of familial resemblance for this anthropobiological character. Ontogenetic and sexual variations has been observed in function of the used filter and the body site of measurement (arm or forehead). Skin colour has a moderate-high heritability, with correlations coefficients varying between 0.28 and 0.45. Likewise, the study has confirmed that the degree of familial similarity of this trait varies with age: in general, arm shows a higher genetic dependence, especially from puberty, whereas forehead is more influenced by environmental factors.Sing up and download the publications of Eusko Ikaskuntza
