河南汉族指纹纹型研究

The study of fingerprint patterns of Han Nationality in Henan

采用随机整群抽样的方法调查了河南汉族指纹样本400份(男女各200人).研究结果显示:①河南汉族A、L、W 3种纹型的出现频率分别为2.13%、48.78%、49.10%,三型指纹的分布存在性别间差异;②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,同名指同类花纹组合A/A、L/L、W/W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;③男性TFRC为143.86±30.15,女性TFRC为135.58±28.74,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;④一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,一手五指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.

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. The results are as follows： ①The frequencies of arch, loop, whorl were 2. 13%, 48.78% , 49. 10% respectively. There is a significant different between sexes in the fingerprint pattern. ② Corresponding fingerprint patterns from high to low was ： W/W 〉 L/L 〉 L/W 〉 A/L 〉 A/A 〉 A/W. A/A, L/L, W/W are compatible, A/W is incompatible. ③TFRC were 143.86 ±30. 15 in male and 135.58 ±28.74 in female. Comparing with other ethnic groups, Han has a middle level in FRC. And there is a significant different between sexes,hands, fingers in FRC. ④In the combined pattern in 5 fingers of one hand showed that higher observed rate in 0, 0, 5 and 0, 5, 0. The homotype combines have very high compatibility and the allotype combines have no compatibility.
