Abstract

Sex identification of archaeological human remains is essential for the exploration of gender differences in past populations. Traditional morphometric analyses fail to identify the gender of incomplete skeletal remains and that of immature individuals. In the present work, we have established a sensitive and reliable method, based on amplification of the single-copy amelogenin-encoding gene (AMG). The Y allele carries a small deletion in the first intron, facilitating the design of distinct X- and Y-specific polymerase chain reactions. Amplification with three primers, two of which are allele-specific, allows unambiguous identification of both X and Y chromosome signals in a single reaction, providing an internal control. For added confidence, the reaction may be performed in separate tubes for each allele. Using this method, the sex was determined from the skeletal remains of 18 individuals, including young children, out of 22 examined from periods ranging from 200 to around 8000 years ago. The state of skeletal preservation ranged from poor to good. Cortical and cranial bones, as well as teeth, were found to provide sufficiently preserved DNA. The success of retrieval of amplifiable DNA was not related either to the period or to the burial site. On the other hand, the method of DNA purification was critical. In our hands, direct DNA purification by Chelex from minute samples of bone/tooth powder gave the best results. This study demonstrates the applicability of the method for gender determination in skeletal remains from different periods.
