Abstract
Bilateral asymmetry is one of the widely used features by proxy as an indicator of environmental and occupational stress and developmental instability. However, its application in personal identification has not been well elucidated in the literature. The present study strives to investigate the forensic implication of fingerprint white line count (FWLC) quantity and asymmetry and the potential of their utilization as complementary tools in personal identification. The objectives of the study were to determine the potential of FWLC asymmetry as a possible feature for sex and left or right of digit determination and its possible forensic implication among the Hausa population of Kano state, Nigeria. The study was a cross sectional type which comprises of 300 participants. A plain fingerprint captured using live scan techniques to determine the FWLC. Wilcoxon signed ranks and Mann-Whitney tests were used to compare the paired and independent variables. Binary logistic regression analyses were employed for determination of sex and left or right of the digit. The result shows statistically significant differences between the left and right FWLC in both sexes. FWLC exhibited leftward asymmetry in all the digits in both males and females. Significant sexual dimorphism in FWLC asymmetry was observed in all the digits except for the middle digits. Regarding the sex and left or right determination, the coefficients of discrimination of sex and left or right of digit were found to be significant for all the digits except for the middle digits for sex. The variance of sex and left or right of the digits explained by FWLC asymmetry was higher for index and ring digits. The group membership prediction was best for index and ring digits. In conclusion, the FWLC asymmetry exhibits potential in sex and left or right of the digit prediction among Hausa population. Index and ring digits were the best digits that expressed the level of dimorphism and discrimination.
