新疆不同地区维吾尔族眼部特征多态性研究

Polymorphisms of the Uygur People's Ocular Features from Different Regions of Xinjiang

在新疆维吾尔自治区内,不同地区的维吾尔族呈现不同颜色的眼色,以黑褐色为主,平均出现率为90.45%;各类浅颜色眼色(天蓝色、灰色、浅绿色、浅黄色)均有一定的出现率,平均出现率为9.55%。从东部(哈密地区)到西部(喀什地区),浅颜色眼色出现率逐渐增加。维吾尔族眉毛生长发育较好,有较高的连眉发生率,从东部到西部眉毛生长逐渐浓密,连眉发生率逐渐增加。上眼睑皱褶表型频率较高,平均62.07%,从东部到西部逐渐下降。内眦褶表型频率平均48.63%,从东部到西部逐渐减少。维吾尔族的眼部特征具有明显的本民族特点,各项指标均介于北亚蒙古人种和欧罗巴人种之间。不同地区的维吾尔族眼部特征表现出一定的差异,并呈从东部到西部逐渐变化的趋势。维吾尔族所表现出的眼部特征与近现代维吾尔族形成的人种构成和演化过程相吻合。

Uygur people from different parts of the Xinjiang Uygur Autonomous Region show various eye colors, the majority of which are dark brown appearing 90.45% of the time. Other kinds of light colored eyes （sky blue, gray, light green, light yellow） have appearance rates that average 9.55%. In general, the appearance frequency of light colored eyes gradually increases from east （Hami） to west （Kashgar）. The eyebrows of Uygur people grow pretty well and have a relatively high rate of eyebrow connection. From east to west, Uygur people＇s eyebrows gradually appear to be bushier and have higher frequency of connection. Among all Uygur peoples, upper eyelid folds have relatively high frequency that average to 62.07%, graduallydecreasing from east to west, while inner canthal folds have a lower frequency with an average 48.63%, gradually falling from east to west. In conclusion, the ocular features of the Uygur people are characteristic of their national identity. All investigated indices of their eyes have values that are inbetween that of the northern Mongolian and Europeans. These ocular features shown by modern Uygur people coincide with their ethnic composition and evolutionary path of their ancestors.
