... ense potential of fingerprints as an effective method of identification an attempt has been made in the present work to analyse their correlation with gender and blood group of an individual. This study was carried out on 100 subjects (50 male and 50 female) having different ABO blood groups and belonging to different age groups. All the 10 fingerprints were taken and divided into loops, whorls, arches and composite. Results show that loops are most commonly found pattern followed by whorls, arches and composite. Loops are predominant in males whereas whorls and arches are seen more in females. Composites being in same proportion in both sexes. Highest frequency of loops was seen in O positive blood group followed by B positive. Among loops ulnar loops were predominant.
