【Abstract】 The finger prints of Tibetans in good health from various counties close to Lhasa city ofTibat Autonomous Region were analysed. There are 517 persons in this sample including 226males and 291 females, aged 12- 19 years. The results obtained ale as follows:1. The frequencies of finger patterns Ws, Wd, Lu, Lr, Asand At(% ± sp) are 46.58 ± 0.69, 8.28± 0.38. 41 .45 ± 0.69, 1.72 ± 0. 18, 1.30 ± 0. 16 and 0.68 ± 0.1 1 respectively. The whorls in male aremore abundant than those in female (p<0.01), while the loops have higher frequencies in fernalethan in male (p< 0.01). There are no differenee in frequency of arches between male and female(P>0.5).2. Furuhata’s index, Dankmeije’s index Pattern intensity index and pattern coefficient are127.08, 3.59, 15.29 and 55.96 respectively.3. Mean total finger ridge count(TFRC) is 149.43 ± 33.53 in male and 136.79± 37.94 infemale. TFRC is of larger number in male than in female (P < 0.01 ).4. Comparison among the Tibetans liVing in different regions suggests that the Tibtans invarious counties near Lhasa city are less different from the Tibetans in Pingwu Region ofSichuan Province and Lhasa City Proper, and more different from the Tibetans in Gannan Region of Gansu Province and in Markang Region of Sichuan Province.5. DifTfrent nationalihes and race were compared. Tibetans showed smaller differeneefrom the Hans and other Mongoloids such as Japanese and greater dmerence from theCaucasians and the Negroes. The results showed that the finger patterns of Tibetans in variouscounties close to Lhasa city of Tibet Autonomous Region have their own special features, andshowed general chalacter shared with the Mongoloids.更多还原
