The discriminant functions of metacarpal and metatarsal bones obtained are generally above 80%, which is similar to reports from other populations. In general terms, the widths of both epiphyses were the most dimorphic measurements. In this case the first metatarsal was the most dimorphic. For metatarsals, five discriminant functions were obtained, ranging from 77.8% to 83.2% of certainty. The second metacarpal was the most dimorphic of the sample. Resultsįourteen discriminant functions were developed for metacarpals with percentages from 79.5% to 85.3% of correct gender classification. Five measurements were taken (maximum length and four widths) of each metacarpal and metatarsal bones employing a digital calliper. The sample belongs to the Autonomous University of Mexico (UNAM) Collection from the Physical Anthropology Laboratory, UNAM Faculty of Medicine. Material and methodsĪn analysis was performed on metacarpal and metatarsals bones of 112 adult contemporary skeletons (49 females and 63 males). The aim of this study was to obtain discriminant functions for estimating gender from direct measurements of the metacarpal and metatarsal bones for identification of unknown individuals.
