This research was made in order to find out if there is an inherited component which determines the features of dermatoglyphics by transmitting inherited information from parents to children. The article shows the results of a research into 22 quantitative features of the digito-palmar complex, and 2 features of the plantar area in 400 persons. No significant differences were found in the parameters of the observed variables between fathers and sons, nor mothers and daughters. The differences were found, however, between fathers and daughters, and mothers and sons. The analysis of the correlation coefficients within the families showed that only the variables TRC and TPRC have polygenic hereditary model. The correlative analyses have shown close links between parents and children, the link between parents and sons being stronger than the link between parents and daughters. The research has not confirmed the thesis about greater overlap between mother and children, than between father and children, set forth by Knussmann in 1973.
