Abstract

Sex determination is vital for the identification of an individual. Success in the sex determination is limited as often fragmentary remains are available for forensic identification. In the present study, 60 adult human skulls of North Indian individuals were studied to assess the reliability of the prominence of supramastoid crest(a non-metric trait) in sex determination, so that sex can be determined from fragmentary crania. The prominence of the supramastoid crest was compared with the casts prepared and standardized by Australian National University. The data was statistically analysed by Logistic and Probit regression models. Subsequent to analysis, it was found that the prominence of supramastoid crest correctly classified 75% of the sample.
