Abstract: The distributive features of white line (WL) in 3597 cases of Mongolian, Han, Hui and Chinese Korean in Inner Mongolia are analysed. The relations between the WL of fingerprint and both wrinkly palmar and palmar flexion are explored. The results show that the frequencies of WL of fingerprint are: Mongolian 12.57%, Han 15.17%, Hui 18.80‰ and Korean 14.78%. For the frequencies of WL of the four nationalities, there are significant differences between sexes, left and right hands, and different nationalities. The relative frequences of wrinkly palmar and palmar flexion of the transitional I type and the Sydney type are higher in the subjects with WL of fingerprint in the four nationalities.
