Abstract

The study investigated earprint and fingerprint patterns among the Urhobos’ and Ibos’ residing in Warri, South Southern Nigeria. The  study was a descriptive crossectional study which involved 40 Urhobos’ and 40Ibos’, aged 18years and above. Ear and fingerprint patterns were obtained with a Hewlett placard G4010 Photo scanner. Chi square test was used for categorical variables and a T test was used to compare means of dermatoglyphic variables. Statistical evaluation was done using SPSS 20 Software Version. Significance was accepted at  P<0.05 Findings showed that the ulnar loop was predominant while the radial loop was least observed in the studied population (70%,1.3%). Earprints that were common in the studied population were Type V and VI (7.5%, 38.8%). Type VII and VIII were frequent in the Ibos’ while Type I and III were perculiar with the Urhobos’ (X2 = 2.804; P = 0.903). The arches found on the left fingers were significantly  different among the two ethnic groups (p= 0.003). There was also a significant difference in fingerprint patterns observed on the left  middle and little finger alongside AFRC of the right and left little finger among the respective tribes (p=0.009; 0.012; 0.031; 0.007). Sexual dimorphism was observed in fingerprint patterns and TFRC among the Ibos’ (p=0.001; 0.001). Ear and fingerprint patterns vary among ethnic groups and can be used in criminology and forensic science.
