Bivariate correlations and multivariate (factor) analysis of pattern intensities on individual fingers and all specified areas of palms and soles were performed in a large sample of 834 individuals from two rural districts of Poland, and in a sample of 383 school children from the city of Warsaw, with males and females considered separately. Eleven factors were extracted in all samples, including two for finger pattern intensities, and the remaining nine for palmar or sole individual areas, or some of their combinations. Patterns of intercorrelation between variables and the factor structure matrices were essentially similar in all subsamples, but several factors differed in the amount of variance they contributed to individual variables, or the factors occupied somewhat different positions when ranked in respect of the contribution to the total variance. Orthogonal and oblique rotation were applied to the data, but only the results of the latter were tabulated and fully discussed. In contrast with finger patterns, separate and independent factors have mainly been extracted for individual pattern intensities on palms or soles. Nevertheless the obtained factor solution on the whole is not incompatible with the concept of developmental induction fields. It is postulated that the factor structure may be susceptible to natural selection acting through functional preferences in man, and that epistatic interaction may account for some common factors.
