宁夏回族、汉族皮纹学研究——Ⅰ指纹

目的 报道指纹各参数在宁夏回族、汉族群体中的分布特点.方法 采用随机整体抽样方法分析宁夏回族、汉族指纹样本共计614份,回族262人(男性129人,女性133人),汉族352人(男性206人,女性146人).结果 两民族间尺侧箕型纹和桡侧箕型纹存在显著性差异;同名指各组合频率按由高到低排序均为W/W＞L/L＞L/W＞A/L＞A/A＞A/W;男性汉族TFRC为137.34±2.01,女性123.60±1.75;男性回族为137.36±2.25,女性120.58±1.91.结论 1.两民族TFRC不存在明显民族间差异,但有显著性别差异;2.两民族间一手五指指端花样类型的递减频率次序除U存在差异外,其他3项无显著性差异;3.A/W具有不相容性;4.不同地区回族群体指纹参数差异显著;5.弓形纹的分布具有明显种族差异.

THE DERMATOGLYPHIC STUDY OF HUI AND HAN NATIONALITIES IN NINGXIA, CHINA——Ⅰ FINGERPRINT

Objective To investigate the characteristics of fingerprint parameters between Han and Hui nationalities in Ningxia, China. The parameters included fingerprint patterns, finger ridge count(FRC),total finger ridge count(TFRC), pattern intensity index(PⅡ), corresponding fingerprint patterns, combined pattern in 5 fingers in one hand.Methods A random sampling was conducted among 614 which comprised 262 Hui (129 male, 133 female) and 352 Han (206 male, 146 female). Inked fingerprint sample were collected and fingerprint parameters were analyzed with informed consent. Results Frequencies of both ulnar loop (U) and radial loop (R) showed significant difference between two nationalities. Corresponding fingerprint patterns from high to low were same in the two nationalities which showed as W/W>L/L>L/W>A/L>A/A>A/W.TFRC in Han were 137.34±2.01 in male and 123.604±1.75 in female, in Hui were 137.36±2.25 in male and 120.584±1.91 in female respectively, In the combined pattern in 5 fingers of one hand, two populations all showed higher observed rate in 0,0,5;0,5,0 and lower observed rate in 0,2,3;0,3,2 et. al.Conclusion There is no significant difference between two nationalities in TFRC but sexes. The digressive order in 5 fingers of one hand appears difference in U, it is more invariableness than the other indexes.A/W is incompatible. There is a significant different fingerprint parameters among different Hui nationalities in China, that may indicate they have different origin. The heritability of arch is 91%, so it distributes different in different populations in the world. The rate of arch
