The fingerprints are very typical for a human being. The present study was undertaken to study the gender differences in fingerprint ridge density in Chinese and Malaysian population. The study done on 200 subjects (100 males and 100 females) of Chinese origin and 100 subjects (50 males and 50 females) of Malaysian origin revealed that significant gender differences occur in the finger ridge density. Fingerprint mean ridge density of 12 ridges/25 mm(2) or less is found to be more likely to be of males and a mean ridge count of more the 13 ridges/25 mm(2) is more likely of female origin in Chinese subjects. Fingerprint mean ridge density of 11 ridges/25 mm(2) or less is found to be more likely to be of males and a mean ridge count of more the 13 ridges/25 mm(2) is more likely of female origin in Malaysian subjects.
指纹非常具有人类特征。本研究旨在研究中国人和马来西亚人群指纹嵴密度的性别差异。该研究对 200 名中国血统的受试者（100 名男性和 100 名女性）和 100 名马来西亚血统的受试者（50 名男性和 50 名女性）进行了研究，结果表明指纹嵴密度存在显著的性别差异。在中国人群中，每 25 平方毫米（2）有 12 条或以下的指纹平均嵴密度更有可能是男性，而每 25 平方毫米（2）有超过 13 条的指纹平均嵴密度更有可能是女性。在马来西亚人群中，每 25 平方毫米（2）有 11 条或以下的指纹平均嵴密度更有可能是男性，而每 25 平方毫米（2）有超过 13 条的指纹平均嵴密度更有可能是女性。
