[Heredity and the bimanual asymmetry of human finger and palm dermatoglyphs].

An attempt has been made to study the effect of hereditary factors on the asymmetry of morpho-functional quantitative traits, in particular, finger and palm dermatoglyphs (24 indices). The results of examination of 140 twin pairs (83 monozygotic and 57 dizygotic) are presented. The hereditary effects have been found for ten traits when an account is taken of the asymmetry direction, and for nine traits when asymmetry direction is not considered.
