Abstract



Background: Bilateral symmetry had been shown to reflect developmental stability in prenatal with practical application in anthropological dermatoglyphics for species or individual identification(s) and also as bio-indicator in mass screening of genetically altered phenotypic expression. This study, therefore aimed at finding the bilateral symmetry in fingers and palmers dermatoglyphics features among the male and female medical students of Bingham University, Karu Nigeria.
Methods: A total number of 62 Medical students comprised 27 male and 35 female students in 300 level were invited for this study. Finger and palm prints were obtained using ink method according to Cummins, which was uniformly smeared on the palmer and finger surfaces of the subjects' hands for complete imprint of the finger and palmer surfaces. Fingers dermatoglyphics pattern types, intensity, ridge counts and palmers ATD, DAT and ADT angles, main line index, a-b ridge counts and axial tri-radii position were symmetrically bserved on the left and right hands in both male and female subjects respectively. Data were analysed by Students t- test using graph pad prism version 6 for both quantitative and discrete data
Results: Insignificant (P>0.05) bilateral symmetry was recorded in axial tri-radial position among the male students, while symmetry arrangement was observed in the number of ridge counts on the left and right among the female Medical students. Nevertheless, insignificant differences or bilateral symmetrical expression of dermatoglyphics traits were observed in the palmer parameters on the left and right in both male and female subject
Conclusion: Symmetrical and asymmetrical arrangement
