Ustalanie płci w populacji Filipińczyków na podstawie gęstości linii papilarnych na płaskich odbitkach

Abstract

Fingerprints are integral in establishing individuality in forensic cases. This study derived sex discrimination formulas using the radial ridge density of plain fingerprints in a sample of 150 male and 150 female Filipinos. Laterality, interfinger differences, and associations between ridge density, height, and weight were examined. Ridge density was found to be sexually dimorphic (p < 0.001), with an average of 17 ridges / 25 mm2 recorded among males and 20 ridges / 25 mm2 among females. Most prints were revealed to be laterally distinct with statistically significant interfinger differences among the sexes. While results confirm that radial ridge density is sexually dimorphic within the sample, comparably higher ridge estimation thresholds were reported in this study than in existing literature – potentially due to the use of plain prints for measuring ridge density. Given representational inequities in forensic research, this study diversifies existing thresholds using a viable yet cost-effective method for estimating sex.
