The study was designed to determine sexual dimorphism among Ebira Ethnic group living in Okene, Kogi state using palm print pattern classification, ATD angle, and ridge density. A total of four hundred subjects (200 males and 200 females) participated in the study. Palm prints were collected using an HP Scanner (Scanjet 300). Chi-square and Pearson correlation were used in analyzing the data and statistical significance was set at p ≤ 0.05. The result of this study showed that the predominant palmprint patterns in males and females were category 5 and category 4 respectively. ATD angle for females was greater than that of the males which showed that ATD angle is sexually dimorphic among Ebira ethnic group while ridge density on the other hand showed no relationship with sex. In conclusion, it is established that palm print classification and ATD angle can be used to determine sex among Ebira ethnic group which will enhance personality identification.
