Background: Finger print (Dactylography / Dermatoglyphic) is considered as the best tool of identification. A reliable personal identification is critical in the subject of forensics as is faced with many situations like civil, criminal, commercial and latest in financial transaction frauds, where the question of identification becomes a matter of paramount importance. In this study we have made an effort to “study a relationship between pattern of fingerprint, gender and blood group”. Study Type: Cross sectional Study. Place of Study: Data was being collected from school going children’s of Narketpally. KIMS Narketpally. Materials and methods: 170 school going children participated in the study voluntarily and their finger prints were collected, of which 82 were males and 88 were females, who were aged between 11 – 16 years. Blood group of each individual was documented, if the blood group wasn’t known then the blood group was identified using antiserum A, B and D. The finger-prints were taken of all ten fingers using printer’s ink. Pattern of fingerprints were observed by powerful hand lens and recorded. Note was made of the sex, age, ABO blood groups. Results: O Rh + ve are the most common blood type, followed by B Rh + ve. High frequency of loops (61.88%), moderate whorls (27.76%), and low frequency of arches (9.88%) with composite (0.47%). Loops are predominant in blood group O and whorls are predominant in blood group B. There is an association between fingerprint patterns, blood group and gender. Conclusion: We may conclude that there is an association between distribution of fingerprint patterns, blood group and gender and thus prediction of gender and blood group of a person is possible based on his/her fingerprint patterns but influence regional variations, gender and genetic factors should not be overlooked.
