Finger prints in sex determination

Abstract

Sex determination is a crucial aspect of personal identification in forensic science and medico-legal investigations. Fingerprints, due to their uniqueness and permanence throughout an individual's lifetime, serve as an important biometric tool for human identification. The present study aimed to evaluate the role of fingerprint patterns in sex determination. A total of 50 fingerprint samples were collected from randomly selected individuals, including 25 males and 25 females. The left index finger prints of females and right index finger prints of males were obtained and analyzed. The fingerprints were classified according to the Edward Richard Henry classification system, which includes patterns such as arch, tented arch, left loop, right loop, and whorl. Statistical analysis was performed using SPSS software to determine the mean deviation and probability inference related to gender differences. The results revealed that 10% of females exhibited left loop patterns, 8% showed right loop patterns, 4% displayed whorl patterns, 2% had arch patterns, and 1% had plain arch patterns. Among males, 9% demonstrated whorl patterns, 8% showed right loop patterns, 5% exhibited tented arch patterns, 4% had left loop patterns, and 2% had plain arch patterns. The findings suggest that left loop fingerprint patterns are comparatively more predominant in females, whereas whorl patterns are more frequently observed in males. Although fingerprint analysis alone may not provide an infallible method for sex determination, it can serve as a valuable supplementary tool in forensic identification and forensic odontology. Further research with larger sample sizes and diverse populations is recommended to strengthen the reliability of fingerprint-based sex determination.
