Background and Objectives: Identification is of paramount importance in medicolegal investigations. Identification means the determination of the individuality of a person. This study involved the recording of lip and fingerprints of 50 males and 50 females in the age group of 18–24 years to assess their distribution in the gender groups and to evaluate the reliability of lip and fingerprint patterns in gender determination. Materials and Methods: The individuals were selected based on the inclusion and exclusion criteria. The procured prints were scanned and analyzed for uniqueness and gender determination using Adobe Photoshop CS5 software (Adobe Systems Incorporated, San Jose, California, USA). Statistical analysis was done using statistical mean, standard deviation, Chi-square test, Student's unpaired t-test (P < 0.05), and Cohen's Kappa test. Results: The most frequent lip print pattern was Type IV in males and Type I' in females. The most frequent fingerprint pattern was ulnar loop in the total population, as well as in the sex-wise distribution. Individuals with mean fingerprint ridge densities in the range of 10–12/25 mm2 were predominantly males whereas those >14/25 mm2 were predominantly females. Conclusion: Fingerprint ridge density was found to be a more reliable tool in estimating the gender of an unknown individual than lip print.
