A Study of Fingerprints in Relation to Gender and Blood Group among Residents of Maiduguri, Nigeria

Abstract

Fingerprints are classified and documented on the basis of ridge patterns. The impressions made by the pattern of any individual remain unchanged throughout life. The study was carried out on 400 individuals among which 200 were males and 200 were females subjects having different ABO blood groups, all the 10 fingerprints were divided into loops, whorl and arches. The results showed that majority of the subjects belonged to blood group O. The finger print pattern of loops had the highest frequency while arches were the least. Blood group O were mostly associated with the loop pattern while AB had the least frequency in all the fingerprint patterns. Males had the highest number with the loops and whorls while females had the highest number of arches. It was concluded that there was an association between distribution of fingerprint patterns, blood group and gender and thus prediction of gender and blood group of a person was possible based on the fingerprint patterns.
