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.
