Distribution and sexual dimorphism of palm print variable (palmer triridii angles) among Hausas of Kano and Zaria Metropolis, Nigeria

Abstract

Dermatoglypics is the study of dermal ridges on finger balls, palm of the hand and sole of the feet, and provides a myriad of genetic information which are pointer to inherited genetic diseases. The aim of the study was to analyze palm prints (palmer triridii angles) among Hausas of Kano and Zaria. A total of 600 subjects comprising of 300 participants from two original Hausa metropolis (Kano and Zaria) with 1:1 male to female ratio participated. Ink method was used to capture palm prints. Chi-square was used to determine the association between the variables. The result of the study showed that a significant gender differences in the mean value were observed in the atd and dat angles in both cities and Hausas of Kano (t=-2.97, p <0.05 for atd, t= 2.59, P< 0.05 for dat) with no significance in the Hausas of Zaria in right hand. However, a statistical significant difference was present in the atd and adt angles in both cities and Hausas of Kano (t=-4.99, p <0.001 for atd, t= 5.09, p< 0.001 for adt). For the Hausas of Zaria only the atd (t=-3.30, p <0.05 for atd) angle shows significant difference. For comparison based on sex, no significant differences was observed between males from Kano and Zaria, and females from Kano and Zaria with respects to dat and adt angles of right palmer triradii. However, a significant difference was observed between Kano and Zaria males with respects to dat and adt angles of palmer triradii respectively.
