Fingerprints are distinct physical characteristics that remain unchanged throughout an individual's lifetime. This study derived Filipino-specific probability formulae from fingerprints to be used for sex discrimination in human identification cases. Ridge density from three different areas - distal radial area, distal ulnar area, and proximal area - as well as white line counts from fingerprints of 200 male and 200 female Filipinos were collected and analyzed statistically. Ridge densities of radial and ulnar areas emerged as displaying significant differences between the sexes, with 16ridges/25mm(2) or more in radial area and 15ridges/25mm(2) or more in ulnar area being more likely to be female, whereas 13ridges/25mm(2) or less in radial area and 12ridges/25mm(2) or less in ulnar area were more likely to be male. A white line count of 0 was more likely to be male while a white line count of 2 or more was more likely to be female. The results of this study show sex differences in Filipino fingerprints and support the observation of previous studies that females have finer ridges than males.
指纹是独特的身体特征，在一个人的一生中保持不变。本研究从指纹中推导了菲律宾人特有的概率公式，用于人类身份识别案件中的性别歧视。收集了200名菲律宾男性和200名菲律宾女性指纹的三个不同区域（桡侧远端区域、尺侧远端区域和近端区域）的嵴密度以及白线计数，并进行了统计分析。桡侧和尺侧区域的嵴密度在性别之间存在显著差异，桡侧区域16条/25平方毫米或更多以及尺侧区域15条/25平方毫米或更多更可能为女性，而桡侧区域13条/25平方毫米或更少以及尺侧区域12条/25平方毫米或更少更可能为男性。白线计数为0更可能为男性，而白线计数为2或更多更可能为女性。本研究结果显示了菲律宾人指纹的性别差异，并支持了先前研究的观察结果，即女性的嵴比男性更细。
