Abstract: 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.

Key words: Somatoscopy; Anthropometry; Hereditary variation; Descendants of Li nationality intermarried with Han nationality
