The Morphometric Study of Sexual Dimorphism in Index & Ring Finger Length Ratio in Indian Population.

ABSTRACT

Background: Anthropometry is a science which deals with method and techniques of measurement of living as well as skeletons of individuals. The morphometry of different parts of human body helps in personal identification and also sexual dimorphism. Methods: Total number of students (200=Male & 200=Female) of age 17-25 years of Teerthanker Mahaveer University were examined for one year. With the help of vernier caliper, the lengths of index and ring fingers were measured and then ratio was calculated in both the genders. The data was tabulated & mean & standard deviation was calculated. The paired t- test was used and P- value was calculated. P value < 0.05 was considered significant. Results: The mean values of male population were found to be right 2D 7.04cm, right 4D 7.20cm, right 2D4D ratio 0.97cm respectively, while in females the mean value were found to be right 2D 6.52cm, right 4D 6.72cm, right 2D4D Ratio 0.96 cm respectively. Using t-test, in males and females the 2D4D ratio was statistically insignificant for the right hand with p>0.05. Conclusion: The anthropometric ratios help in establishing the gender and race of the individual, thus plays an important role in forensic science.
