[The intertriradial dermal ridges and their relation to handedness].
Palm prints of 394 right-handers and 356 non-right-handers (left-handers and ambidextrous) were evaluated regarding intertriradial ridge counts. Comparison between the handedness groups produced no significant differences. There were found partly contrary tendencies in males and females. The values of an elected group of extremely left-handed females indicate a relation between a "graded variety of handedness-distinction" and a "graded distinction of dermatoglyphic traits". Earlier indications that bilateral asymmetry is reduced in left-handers could not be confirmed generally.
