Abstract

The aim of this study is to determine whether or not the breed and sex factors have an effect on the shape in the mandibles of Hamdani and Awassi sheep. A total of 31 mandibles were used. The samples were analyzed via geometric morphometric methods by using semilandmark. In the study, it was determined that the primary principal component accounted for 36.52% of the total shape difference. According to principal component analysis, samples were clustered significantly in terms of breed; whereas, they were not clustered in terms of sex. In terms of the primary principal component, the places where the shape differences were concentrated were the attachment sites of teeth to the mandible, between the second molar and ramus mandible, the processus coronoideus and the angulus mandible. Mandible of Hamdani sheep had a higher body than the mandible of Awassi sheep. Mandible of male sheep was more voluminous than mandible of female sheep, especially in the body area. Consequently, it is thought that the data obtained as a result of the study would serve as a reference for the ruminant mandible remains obtained from archaeological excavations.

Hamdani和Awassi绵羊下颌骨的半定标几何分析

本研究的目的是确定品种和性别因素是否对Hamdani和Awassi绵羊下颌骨的形状有影响。共使用了31个下颌骨。样品采用几何形态计量方法，用semiland标记进行分析。在研究中，确定主要主成分占总形状差异的36.52%。根据主成分分析，样本在品种方面具有显著的聚类性；然而，他们并没有按性别分组。就主要主成分而言，形状差异集中的部位是牙齿与下颌骨的附着部位、第二磨牙与下颌支之间、冠突与下颌角之间。Hamdani绵羊的下颌骨比Awassi绵羊的下颌骨高。雄性绵羊的下颌骨比雌性绵羊的下颌骨更大，尤其是在身体区域。因此，人们认为，作为研究结果获得的数据将作为考古发掘中获得的反刍动物下颌骨遗骸的参考。
