We have analyzed dermatoglyphic finger patterns in a Spanish Basque population (841 males and 911 females). Bimanual and sexual comparisons have been carried out by means of contingency analysis. The results in the Basque population are compared with those of other Spanish populations, based on univariate (chi 2 contingency test and Student's t-test) and multivariate (principal components analyses) statistical methods. Bilateral distribution asymmetry and sexual dimorphism were observed in the Basque sample. The results of the chi 2 test for pattern types in males and females show statistically significant differences between the Basques and other Spanish populations, with the exception of the males from El Bierzo. Comparing populations with regard to the Pattern Intensity Index, the differences observed are much lower; therefore, this confirms what other authors have suggested regarding the limited usefulness of indexes in populational comparisons. In the Caucasian variation range of pattern types, Basques are located in the high part with regard to arches, in the low part with regard to whorls and radial loops, and in an intermediate part in relation to ulnar loops and overall pattern intensity. Results of the multivariate comparisons show which populations are more or less distant from the Basque population and which variables are significant in contributing to these population relationships.
我们分析了西班牙巴斯克人群（841名男性和911名女性）的皮纹指纹模式。通过列联分析进行了双手和性别比较。基于单变量（卡方列联检验和学生t检验）和多变量（主成分分析）统计方法，将巴斯克人群的结果与其他西班牙人群的结果进行了比较。在巴斯克样本中观察到双侧分布不对称和性别二态性。男性和女性指纹类型的卡方检验结果显示，巴斯克人与其他西班牙人群之间存在统计学上的显著差异，但埃尔维索的男性除外。就指纹强度指数比较人群时，观察到的差异要小得多；因此，这证实了其他作者关于指数在人群比较中有用性有限的观点。在高加索人指纹类型的变化范围内，巴斯克人在弓形纹方面处于较高水平，在斗形纹和桡侧箕纹方面处于较低水平，在尺侧箕纹和整体指纹强度方面处于中间水平。多变量比较的结果显示了哪些人群与巴斯克人群的距离或多或少，以及哪些变量对这些人群关系有显著贡献。
