黎族、汉族通婚后裔体征的遗传变异

从“t”值测验表明,黎汉通婚后裔在形态特征上有些变化。与黎族相比,蒙古褶出现率显著增多,上眼睑皱褶发育明显减弱;与汉族相比,波形鼻梁明显增加,上翘型鼻尖和鼻基底显著增多,水平型明显减少。从测量性特征的比较表明,通婚后裔在体征上较多地显示汉族的性状,比黎族更接近于汉族。

THE HEREDITARY VARIATION OF THE DESCENDANTS OF LI NATIONALITY INTERMARRIED WITH HAN NATIONALITY IN PHYSICAL FEATURES

Main hereditary variations of the descendants of Li nationality intermarried with Han nationality living in Hainan Island from this study are as follows. Judging from "t" values we can see that some features of the descendants are like neither Li nationality nor Han nationlity. The head length, the height of subnasal-gnathion and the height of the upper integumentary lip are shorter in the descendants than those of Li and Han nationalities. However, some features are markedly different from Li nationality but close to Han nationality, and another features are different from Tan nationality but close to Linationality. On the whole, the physical features of the descendants of Li nationality intermarried with Han nationality are basically similar to those of Han nationality.
