In the past decades ancient DNA research has brought numerous insights to archaeological research where traditional approaches were limited. The determination of sex in human skeletal remains is often challenging for physical anthropologists when dealing with incomplete, juvenile or pathological specimens. Molecular approaches allow sexing on the basis of sex-specific markers or by calculating the ratio of DNA derived from different chromosomes. Here we propose a novel approach that relies on the ratio of X chromosome-derived shotgun sequencing data to the autosomal coverage, thus establishing the probability of an XX or XY karyotype. Applying this approach to the individuals of the Upper Paleolithic triple burial of Dolní Věstonice reveals that all three skeletons, including the individual DV 15, whose sex has long been debated due to a pathological condition, were male.
在过去几十年里,古代DNA研究为传统方法受限的考古研究带来了诸多深刻见解。对于体质人类学家而言,在处理不完整、幼年或病理标本时,确定人类骨骼遗骸的性别往往具有挑战性。分子方法能够基于性别特异性标记或通过计算来自不同染色体的DNA比例来进行性别鉴定。在此,我们提出一种新方法,该方法依赖于X染色体来源的鸟枪法测序数据与常染色体覆盖度的比例,从而确定XX或XY核型的概率。将此方法应用于Dolní Věstonice旧石器时代晚期三重墓葬的个体,结果显示所有三具骨骼均为男性,包括因病理状况其性别长期存在争议的个体DV 15。
