【摘要】：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/WL/LL/WA/LA/AA/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.
[Abstract]:400 fingerprints of Han nationality in Henan Province (200 males and 200 males) were investigated by random cluster sampling. The results showed that: (1) the frequency of W and W patterns was 2.13%, 48.78% and 49.10%, respectively. there were gender differences in the distribution of three types of fingerprints. (2) the order of the frequency of each finger combination from high to low is as follows: W 鈮，
