Abstract
Biological profiling of unknown human remains is the foremost task required in forensic/medico-legal death investigations and sex determination of such remains is an important element of biological identity of an individual. In present study, 12 anthropometric measurements were recorded on 298 Uttarkashi individuals (150 males and 148 females) between age group of 18-25 years. Majority of measurements were found to have a significant degree of sexual dimorphism among them; being highest for cubit and thumb lengths and lowest for left palm and right foot lengths (p >0.001). From Univariate discriminant function analysis, cubit length and left foot length were selected as the best variables to discriminate sex of about 80% (84% males and 76% females) 79% (84.7% males and 73.6% females) individuals, respectively. Similarly, 86% subjects could be classified to their correct sex category from all the lineal measurements (88.5% males and 87.2% females) or the hand measurements only (83.1% males and 84.6% females) from the multivariate discriminant function analysis. The results of present study can be considered an addendum to the existing population data for forensic anthropological literature.
Highlights
Forensic anthropology involves the application of anthropological knowledge, research and techniques in medico-legal contexts for identification purposes
Right foot length (FLR) showed highest index of sexual dimorphism, followed by palm length of left hand, cubit length of right hand and so on; the least index was exhibited by head length, morphological facial height and nose length
Left cubit length and foot length showed highest value of R-square, Eigen value and canonical correlation coefficient, followed by right cubit length and left thumb length, signifying that these variables are highly correlated with sex of an individual
Summary
Forensic anthropology involves the application of anthropological knowledge, research and techniques in medico-legal contexts for identification purposes. Present study was formulated to investigate the degree of sexual dimorphism and; sex estimation accuracies of 12 bodily linear dimensions of head, hand and foot of adult Uttarkashi individuals.
