景颇族指纹纹型的分布

Distribution of fingerprint patterns of Jingpo nationality in China

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（1．49og），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。

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 signifi- cant 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/L（35. 31%）〉 L/W（15. 02%）〉A/L（3. 60G） 〉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 personr 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.
