目的:研究正常景颇族人的指纹纹型分布,为医学、遗传学、人类学提供正常参数.方法:在知情同意原则下,捺印调查对象的手纹.结果:W占49.95％,L占44.67％,A占5.38％,A及L的分布有性别差异.A多见于示指,Lu多见于小指,其次是中指,Lr多见于示指,W多见于拇指,其次是环指.对应指纹型组合频率为W/W(41.75％)＞L/L(35.31％)＞L/W(15.02％)＞A/L(3.60％)＞A/A(2.84％)＞A/W(1.49％),一手五指纹型组合频率为OLW(59.09％)＞同型组合(24.73％)＞ALW(10.82％)＞ALO(4.27％)＞AOW(1.09 ％),双手十指同纹型频率为17.09％.结论:指纹纹型分布具有对称性,与其他民族相比有共性也有其特异性.%Objectiv: To study the distribution of fingerprint patterns in 550 normal people of Jingpo nationality, and to pro vide normal parameters for medicine, genetics and anthropology. Methods: The ink prints of fingerprint and palmar patterns were obtained with informed consent. Results: The frequency of W was 49. 95%, that of L was 44. 67%, and that of A is 5. 38%. There were significant differences in the frequency of A and that of L between genders, while there was no significant difference in that of W between genders. A was mainly distributed in the index fingers, Lu in the little and middle fin gers, Lr in the index fingers, and W in the thumb and ring fingers. The frequencies of the combinations of corresponding fin gerprint patterns were W/W(41. 75%) > L/LC35. 31%)> L/W(15. 02%)>A/L(3. 60%)>A/A(2. 84%)>A/W (1. 49%), those of the combinations of the fingerprint patterns in one hand were OLW(59. 09%)>same types of combina tions (24. 73%)>ALW(10. 82%)>ALO(4. 27%)>AOW(1. 09%), and were 17. 09% of the same fingerprint patterns of a person s two hands. Conclusion: The distribution of fingerprint patterns of Jingpo nationality is bilateral symmetry, and has the same features as other nationalities as well as its special characteristics.
