Background: Dermatoglyphics is referred to as study of the friction ridge formation that appears on the palms of the hands and soles of the feet. There have been works done by different researchers on dermatoglyphics in the field of medicine which has helped in the detection of diseases like breast cancer, anemia. Objective: This study was aimed at determining the Palmar Ridge Counts of the Igbos’ and Okirikas’ in Southern Nigeria. Materials and Methods: The study was non-experimental and analytical. Two hundred subjects selected by simple random sampling. One-way Anova was done using SPSS twenty version. Results and Discussion: The Igbo males with AB ridge count 38.3±4.9156 on the left hand while 37.3± 5.5698 for Okrika males. The Igbo males had BC ridge count 27.4± 5.3560 on the left hand while Okrika males had BC ridge count of 25.0±6.0527. The Igbo males had CD ridge count of 36.0 ±9.1109 on the right hand while Okrika males had CD ridge count of 33.5± 7.3289. Test of significance showed significant difference between the Right CD, Left AB and Left BC Ridge count of Igbo and Okrika subjects (P<0.05). Conclusion: The study has shown the palmar ridge counts of the Igbos and Okrikas. It also showed traces of sexual dimorphism in both populations and explicitly revealed that both populations have nothing to show common ancestry, the similarity seen may have occurred by chance which further implies that both populations could be regarded distinct and unrelated entities
