Finger and palm prints of 126 male and 55 female Yoruba are reported using both quantitative and qualitative procedures. In general, the Yoruba fit into established geographical gradients for sub-saharan African populations. Whorl frequencies on the digits are relatively low, as is the frequency of palmar patterning. Finger ridge-counts, those of males in particular are high by African standards, and much higher than the previously reported data from Nigeria. Due to the lack of data on patterns of geographic variation in total finger ridge-count, little can be made of these findings at present.
本文报告了126名男性和55名女性约鲁巴人的指纹和掌纹，采用了定量和定性两种方法。总体而言，约鲁巴人符合撒哈拉以南非洲人群已确立的地理梯度分布。手指上的涡纹频率相对较低，掌纹频率也是如此。指纹嵴数，尤其是男性的指纹嵴数，按非洲标准来说较高，且远高于此前尼日利亚报告的数据。由于缺乏总指纹嵴数地理变异模式的数据，目前这些发现难以得出更多结论。
