La semejanza familiar en la morfología corporal de la población de Vizcaya

Abstract

This research covers a study about familiar resemblance among three sibling samples and one parent-child sample drawn from the Bizcayan population, taking into account a set of morphologic features which describe the body morphology. The method of analysis is based on the implementation of familiar correlations using maximum lakelyhood estimates (Rao et al., 1987). The coefficients of genetic determination obtained ranged from62.3% to 53.2% according to each different variable. There is no evidence of sex-linkage in any of the biological features considered, although some of them seem to share a greater degree of autosomic genetic determination both in males (adiposity indexes) and females(endomorphy). Somatotypes show a moderate degree of heritability, similar to other Caucasoid populations. Moreover, as a consequence of the common way of life, siblings tend to resemble more to each other than in relation to their parents
