Dermatoglyphics concerns the configuration of epidermal ridges of the volar surfaces of the fingers, toes, palms and soles. The aim of this study is to determine the asymmetry of dermal ridges and palmar variables of atd angle (angle between the triradia a, t and d), a-b ridge count (ABRC) and total finger ridge count (TFRC) of dermal ridges for the Ijaw people of Nigeria. 200 healthy students who are Ijaws were studied. Ink prints of their fingers and palms were obtained. Counting and classifying of palmar and digital ridge pattern configurations of arches, loops and whorls was based on standard techniques. Ijaw males have higher TFRC than the females (p <0.001). The males have lower ABRC than the females (p < 0.005). The males have higher atd angles than the females (p < 0.05). The digital variables of arch, whorl as well as loop and palmar variables such as atd angle and ABRC were distinct in each individual. Hence they may be useful in personal identification. Dermatoglyphic traits may be used in identifying an individual’s gender. The results of this study are compared with similar studies for the Ijaws and other ethnic groups in Nigeria.
