Background: The importance and usefulness of dermatoglyphics in crime investigation, anthropology and disease prediction have been stressed wide published. However, there is dearth of information on the use of palmar creases as an adjunct tool in the prediction of tribe/ethnicity and ancestral relationship among populations. Hence, this study was aimed at predicting ancestry and tribal/ethnic relationship and genetic link among the Urhobo, Isoko and Ogoni ethnic groups using palmar creases. Materials and Methods: In this cross-sectional, observational and analytical study, 360 subjects- 180, 105 and 75 Urhobo, Ogoni and Isoko subjects were sampled via a multi-stage sampling technique to ensure randomization. Palm print was obtained using Oghenemavwe and Osaat (2015) dermatoglyphic capture method. Statistical analysis was performed using Statistical Package for the Social (SPSS IBM version 23.0). Results and Discussions: Using the Ogoni as a reference tribe, the study (Table 1) showed Pearson's Chi-square Analysis for tribe-associated differences in the distribution of pattern based on type/pattern of head of origin of the major palmar creases on the right and left palms, and this was not statistically significant on both palms. But in Table 2a (tribe-associated differences in the distribution of the general shape/appearance of palmar creases on the right and left palms) was observed to be statistically significant (X2 = 73.283, P = 0.001 for right; X2 = 47.786, P = 0.001 for left) and Table 3a showed that tribe-associated differences in the distribution of Middle longitudinal crease on the right and left palms was statistically significant (X2 = 18.135, P = 0.001 for right; X2 = 36.401, P = 0.001 for left). Conclusion: Middle longitudinal crease in particular and general shape/appearance of palmar creases are discriminatory in distribution amongst the tribe studied and thus suggest a tribal/ethnic relationship and genetic link and common ancestry between the Isoko and Urhobo tribes.
