Determination of Gender from Index and Ring Finger Ratio in Young Adult

Abstract

Introduction: Forensic anthropologists are mostly involved in establishing human identification of unknown dismembered remains, especially during the global humanitarian and medico-legal crisis.

Methods: A cross-sectional study was conducted on 250 adults (105 males and 145 females) Nepalese adults in the age group of 20-25 years were studied to investigate sexual dimorphism of the index and ring finger ratio.

Results: The difference between the mean 2DL in males and females was 0.58 in the right 2DL and 0.6788 in the left 2DL. Similarly, it was 0.684 in the right 4DL and 0.714 in the left 4DL which showed not much difference significantly. The index and ring finger ratio is derived by dividing the index finger length by ring finger length Percentage accuracy based on sectioning point analysis in right-hand male was 99.16% and left hand was 99.84% similarly in the female right hand was 99.85% and left hand was 99.46%.

Conclusions: Unlike previous studies, the difference in the length and ratio of the index and ring fingers was not significant between males and females. To generalize the findings, a similar study with a larger sample size is advised.
