689 pairs of sibs from a Polish population are analyzed for the occurrence of the major dermatoglyphic patterns on each of the ten digits. Correlations between pairs of brothers, pairs of sisters, and brother-sister pairs, were calculated for the occurrence of whorls, ulnar loops, radial loops, either kind of loop, and arches on specific fingertips.Except for total loops, sister-sister correlations were lower for all patterns than those for other classes of sib pairs. The correlations obtained for all patterns suggest that pattern form cannot be explained readily by a number of polygenes of equivalent dominance. Monogenic or oligogenic determination, with a large nongenetic component, provide a more likely explanation.
