    Abstract:
    The study reconstructs the sex ratio of 121 stillborn and neonate individuals from the early modern burial site Aegerten, Switzerland. The immature individuals, who were not baptised before death, were buried along the walls of the church. To perform a molecular sex identification, bone samples from the infants were collected from different skeletal elements. Ancient DNA (aDNA) was isolated by a combination of automated phenol/chloroform extraction and precipitation with silica powder. A combination of manuell Chelex extraction and purification kit was also used to perform an extraction. Finally, the aDNA extracts were amplified with a primer system that amplifies a part of the amelogenin gene located on the human sex chromosomes. The morphometrical sex determination of the children suggests a large disproportion of female individuals (about 60%). This finding was compared to PCR-based amplification results. In contrast, the results of the molecular sex identification were a high proportion of male individuals. Looking at these results, it should be noted that the high mortality of male individuals during the last months of pregnancy and during the first month after birth is in accordance with the natural sequence of death also found in recent populations.
