Determination of individuality is one of the prime concerns in forensic investigation. The study of fingerprints is widely used in providing a clue regarding identity. The present study was undertaken to study the sex differences in fingerprint ridge density in the Indian population. The study done on 100 males and 100 females revealed that significant sex differences occur in the fingerprint ridge density. The present study shows a statistically significant difference in fingerprint ridge densities of male and female fingerprints in people of Indian origin. A mean fingerprint 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 12 ridges/25 mm(2) is more likely to be of female origin.
个体识别是法医调查的主要关注点之一。指纹研究被广泛用于提供有关身份的线索。本研究旨在探讨印度人群指纹嵴密度的性别差异。对100名男性和100名女性进行的研究表明，指纹嵴密度存在显著的性别差异。本研究显示，印度裔人群中男性和女性指纹的嵴密度在统计学上存在显著差异。发现平均指纹嵴密度为12条/25平方毫米或更低更可能是男性的，而平均嵴数超过12条/25平方毫米更可能是女性的。
