Study of Fingerprint Patterns in Relation to Gender and Blood Groups in Navi Mumbai, India

Introduction: Human identification can be made by using various physical and mental characteristics. Being unique, fingerprints can be used to identify an individual. The fingerprint is a greasy and oily impression of the friction ridges of the finger. A strong correlation has been found in earlier studies between the fingerprint pattern and gender and blood group.

Objectives: The objective of the study was to determine the correlation (if any) between the fingerprint pattern and blood group and gender.

Materials and Methods: The study was conducted on 170 subjects [70 males and 100 females] in the age group of 18-65 years. The fingerprint pattern of the study participants was compared with the gender and ABO-Rh blood group after taking their verbal consent.

Results: Amongst the ABO blood group, the most common blood group was B (36.47%), followed by O (35.88%), A (18.23%) and AB (9.4%). Rh + ve was the most common rhesus factor (95.88%). The loop was the most common pattern (62.35%), followed by whorl (32.94%) and arch (4.7%). There was a significant association between the fingerprint pattern and the ABO blood group (P-value < 0.05).

Conclusion: The present study confirms that loop is the most common fingerprint pattern while arch was the least common. The study revealed a significant association between the fingerprint pattern and the ABO blood group. No statistically significant association was found between the fingerprint pattern and gender.
