Background: Dermatoglyphic features due to its permanency, genetic influence as well as number of easily observable and measurable characters may be considered one of the most suitable parameters for population variability and have been used extensively to characterize differentiate human populations, hence, are highly suitable for studying population variation. Materials and Methods: A total of 600 subjects comprising of 300 participants from two Hausa metropolis (Kano and Zaria) with 1:1 male to female ratio participated. Ink method was used to capture Thumbprints and Palm prints. Chi-square was used to determine the association between the variables. Results: The result of the study showed no statistical significant differences in frequency distribution of thumbprint pattern in the Hausa population. Similarly, in male participant no statistical significant difference in the frequency distribution among the two Hausa state. However, a statistically significant difference (Z= -2.05, P= 0.04) was observed in the frequency distribution of the left and right thumbprint pattern of the middle finger in the female of Kano state. With regards to palmer creases type no statistical significant differences between the frequency distribution of the right and left hand in both male and female of the two metropolis. A significant difference (t= -2.18, P=0.03) was observed in the mean of triradii angles (adt angle) of the left and right palmer angles in male Hausa Ethnic Group of Kano State. However, no such differences occur in the females of the two Hausa metropolis. Conclusion: The study reveals the potential of thumbprint asymmetry in sex differences among Hausa ethnic group in Kano and Zaria, Nigeria.
