河南汉族指纹纹型研究

A Study of Fingerprint Patterns of Han Nationality in Henan

为了研究河南汉族人群指纹模式样本的参数,采用随机整群抽样的方法分析河南汉族指纹样本400份(男女各200人),得到如下结果:河南汉族A、L、W三种纹型的出现频率分别为2.13%、48.78%、49.10%;各同名指组合频率由高到低排序为:W/W>L/L>L/W>A/L>A/A>A/W;男性TFRC为143.86±30.15,女性TFRC为135.58±28.74;一手五指同类花纹的占30.38%,其中多是同为W或同为L,未见五指全为A者.由此可知:河南汉族三种指纹的分布存在性别间差异;同名指同类花纹组合的观察频率均高于期望频率,表现为同类花纹组合的亲和性,A/W具有不相容性;河南汉族TFRC跟我国部分其他地区汉族及少数民族相比处于中等水平,FRC的分布有着性别、手别、指别的显著性差异;一手五指花纹A、L、W组合,同型花纹组合观察频率增高,而异型组合观察频率降低,A与W不相容.

In order to investigate the characteristics of fingerprints of the Han people living in Henan province, a sample of 400 middle school students （200males, 200 females） of Han nationality were investigated on the fingerprint patterns which were taken with informed consent. Results were as following： The frequencies of arch, loop, and whorl were 2.13%, 48.78% and 49.10% respectively. Corresponding fingerprint patterns from high to low was： W/W）L/L）L/WA/L） A/A）A/W. TFRC were 143.86±30.15 in male and 135.58±28.74 in female. The frequency of fingerprint patterns of all W or all L in one hand were 30.38%, and that of all A was not found in this study. There was a significant sexual difference in the fingerprint pattern. A/A, L/L, W/W were compatible, A/W was incompatible. Compared with other ethnic groups, Han had a middle level in FRC, and there was a significant difference between sexes, hands, and fingers in FRC. The homotype combines in 5 fingers of one hand had very high compatibility and the allotype combines had no compatibility, A/W was incompatible.
