奉贤县东西部2个人群的体质差异

从历史学的材料看，上海奉贤县金汇镇的居民主要是南方土著居民，头桥镇的居民主要是从北方迁徒过来的，二地方言有很明显的差异，对金汇，头桥2个群体的头面部特征，体部特征和肤纹3大类65项观察测量特征进行了比较，以此对2群体间的差异进行了显著性测试，发现2群体间大部分项目有显著差异，说明语言差异能反映遗传差异的观点是有根据的，2个群体的差异可能是因为其来源的不同引起的，在所有特征中，鼻部特征，眼部特征，颧骨，额骨体现的群体间差异最大，提示这些特征可能是面貌遗传研究的突破口。

Physical Discrepancy Between Two Populations in East and West Fengxian County

The populations in Shanghai have always been associated with immigrations,large or small,in the last several thousand years. Historical records revealed that most of the inhabitants of the town of Jinhui in west Fengxian county are natives while the inhabitants of the town of Touqiao in west Fengxian county are the immigrants from north China. The dialects of Jinhui and Touqiao are clearly distinguishable. Out of the 65 observational or metrical features of face, body and dermotoglyphy, a large proportion of them are noticeably different between the two populations. Among all the characters studied, those of eye,nose,chin and jaw show the most signifficant difference between the populations, implying relatively large genetic contribution to their inheritance. It is also suggested that linguistic difference is one of the best social economic factors that may reveal the genetic difference between the populations.
