Sex variation in fingerprint ridge counts in Filipinos

2017, European Journal of Forensic Sciences

Abstract

Objective: The aim of this research was to derive probability formulae based on ridge counts (RC) that could be used to contribute to sex determination in human identification. Methods: A modified technique of obtaining RC that is not influenced by finger patterns was employed. RC from fingerprints of 200 male and 200 female Filipinos aged 18-57 years were collected and analyzed statistically. Results: Males had lower RC compared to females, and there were differences in RC per digit as well. Odds for sex discrimination were obtained for the thumb (
