Abstract: The finger and palm prints of 754 individuals (Li nationality：406 males and 152 females, Lingao people: 96 males, Han tribe: 100 males) were studied.
The main characters of the finger and palm prints of the Li nationality (male) are as follows: finger print: whorl 49.56%, ulnar loop 45.00%, radial loop 2.76%, arch 2.68%, TRC 144.68； main line A： 1 type 20.57%, 3 type 67.24%, 5 type 12.19% ； main line B : 3 type 8.00%, 5 type 65.52%, 7 type 25.00%, 9 type 148%; main line C： ulnar 67.49%, radial 19.09%, proximal 8.37%, absent 5.05% ； main line D: 7 type 38.42%, 9 type 36.70%, 11 type 24.88%, more frequent 7 type than 9 type; MLI 6.62, a-bRC 37.27, PIP 1.23, axial triradius： t 78.29%, t' 21.33%, t〃0.37%; atd 38.57, simian line 10.10%.
In Lingao male, the main trends of finger and palm prints are: finger print: whorl 43.85%, ulnar loop 50,73%, radial loop 3.44%, arch 1.98%, TRC 140.48; main line A： 1 type 25.52%, 3 type 62.50%, 5 type 11.98%; main line B: 3 type 8.85%, 5 type 68.75%, 7 type 21.35%, 9 type 1.04% ； main line C: ulnar 67.71%, radial 17.19%, pro_x001F_ximal 9.38%, absent 5.73% ； main line D： 7 type 38.54%, 9 type 39.58%, 11 type 21.88% ； MIL 6.47, a-bRC 38.19, PIP 1.25, axial triradius： t 85.79%, V 14.24%, t" 0, atd 38.18, simian line 14.06%.
According to t test, ehi-square and cluster analysis, we can come to following conclusion :
Some characters of the palm print of the Li nationality show a possibility of having existed mixed-blood between the Li nationality and Negro.
In four branches of the Li nationality (Ha Li, Qi Li, Meifu Li and Bendi Li), Ha Li is the best representative in aspect of the main finger and palm print characters. This branch is similar to Qi Li, but Ha Li and Qi Li differ more markedly from Meifu Li and Bendi Li in main finger and palm print characters.
Lingao people are similar to the Han nationality, and differ from Zliuang nationality of Guangxi Zhuang Autonomous Region in main finger and palm characters.
