Sexual variation in fingerprint types and pattern size, as measured by total ridge counts, has been examined in a sample of 84 Australian aborigines and compared with other populations. As it generally happens in a population, total ridge counts have been found to be higher in males than females on account of (1) the males' higher frequency of whorls and lower frequency of loops, and (2) the males' larger whorl counts. The higher incidence of arches in females than males has also been found to play a role.
La variabilità sessuale delle impronte digitali è stata esaminata in un campione di 84 aborigeni australiani raffrontato con altre popolazioni. Come si verifica in genere in una popolazione, il numero totale delle creste è risultato più elevato nei maschi che nelle femmine a causa (1) della maggiore frequenza di vortici e minore frequenza di anse nei maschi e (2) dei più elevati conteggi nei vortici dei maschi. È stata anche riscontrata una maggiore frequenza di archi nelle femmine che nei maschi.
La variabilité sexuelle des empreintes digitales a été examinée dans un échantillon de 84 aborigènes australiens comparé avec d'autres populations. Comme il se vérifie généralement dans une population, le nombre total des crêtes a été trouvé plus élevé chez les hommes par rapport aux femmes à cause (1) d'une fréquence plus élevée de tourbillons et moins élevée de boucles chez les hommes et (2) d'un plus élevé nombre de crêtes dans les tourbillons des hommes. Un rôle est aussi joué par une fréquence d'arcs plus élevée chez les femmes.
An einem Muster von 84 australianischen Eingeborenen wurden bei beiden Geschlechtern die Fingerabdrücke untersucht und die Ergebnisse mit anderen Bevölkerungen verglichen. Wie allgemein bei einer Bevölkerung war die Gesamtzahl der Hautleisten bei den männl. Individuen höher als bei den weibl. und zwar weil (1) Männer mehr Wirbel und weniger Schleifen aufweisen, (2) die Wirbel bei Männern zahlreichere Leisten haben. Ein Rolle spielt dabei auch, dass Bögen bei Frauen häufiger vorkommen als bei Männern.
