Dermatoglyphic features of 200 male and 200 female normal Southern Nigerian negroes have been analysed. The frequency distributions of fingerprint patterns, digital and total ridge counts TRC, a-b scores and atd angles are given. In common with other races, the Southern Nigerian population showed the tendency for females to have more arches than males. Like the Zulus of Southern Africa, Southern Nigerian Negroes showed a significant sex difference in the atd angle but the Southern Nigerians have a significantly higher TRC than those previously reported for the Zulu. This study, contrary to previous studies, suggests that low TRC is not a negroid dermatoglyphic trait.
对200名尼日利亚南部正常黑人男性和200名女性的皮纹特征进行了分析。给出了指纹模式、指嵴数和总嵴数（TRC）、a-b分数以及atd角的频率分布。与其他种族一样，尼日利亚南部人群中女性的弓形纹比男性多。与南非祖鲁人一样，尼日利亚南部黑人在atd角上存在显著的性别差异，但尼日利亚南部人的TRC明显高于之前报道的祖鲁人。与之前的研究相反，这项研究表明低TRC并非黑人的皮纹特征。
