Digital dermatoglyphics of an indigenous sample of 87 males and 101 females from the Urola Valley in the Spanish Basque Country are compared with those from the nine other Basque valleys previously analyzed. In both sexes of the Urola Valley, there is a very high frequency of radial loops; the mean found in this valley extends the range of variation for South European-Mediterranean populations, and it is in the superior limit of all Caucasian populations. There are bimanual and sex differences in the frequencies of whorls and loops. Contrary to what occurs normally in populations, in the Urola Valley the frequency of whorls is higher in females and the quantitative value of digital patterns is lower in males. The results of this study show the existence of heterogeneity among valleys for digital trait frequencies and for finger ridge count, and this heterogeneity is more marked in females.
对来自西班牙巴斯克地区乌拉山谷的87名男性和101名女性的本地样本的数字皮纹特征与之前分析过的其他九个巴斯克山谷的样本进行了比较。在乌拉山谷的男性和女性中，桡侧箕形纹的出现频率都非常高；在该山谷中发现的平均值超出了南欧-地中海人群的变异范围，处于所有高加索人群的上限。在箕形纹和斗形纹的出现频率上存在双手差异和性别差异。与人群中的正常情况相反，在乌拉山谷中，女性的斗形纹频率较高，而男性的数字模式定量值较低。这项研究的结果表明，在不同山谷之间，数字特征频率和指纹嵴计数存在异质性，并且这种异质性在女性中更为明显。
