Palmar Dermatoglyphis in ABO Blood Groups

Fingerprint is one of the oldest, reliable and mature biometric technologies and is considered one of the best, cheapest and legitimate proofs of identification. A correlation between physical characteristics like fingerprints and blood group was demonstrated in previous studies.

Objective: To correlate between palmar dermatoglyphics patterns in ABO, Rh blood groups and evaluate their significance.

Methodology: A total of 200 Hymamshu Jyothi kalapeetha students with known blood groups were selected. Fingerprints were obtained by printing method. The distribution of dermatoglyphic fingertip patterns in both hands of individuals and its relationship with gender and different ABO and Rh blood groups was evaluated and analysed statistically.

Results: Blood group O positive is the dominant blood group and AB negative is the rarest. The commonest pattern of fingerprint was loops. Percentage of whorls, loops is highest in AB and O group respectively. The distribution pattern of the fingerprint was of the same order in individuals with A, B, AB and O blood groups i.e high frequency of loops, moderate of whorls and low of arches.
