The association between fingerprint patterns and blood groups in the Omani population

Abstract

PurposeFingerprints and blood samples are important for the identification of individuals and criminals. The present study aims to identify the predominant fingerprint patterns and the association between the fingerprint patterns and ABO–Rh blood groups in Omani population.Design/methodology/approachA cross-sectional study was conducted on 200 Omani individuals aged 18 years (104 males and 96 females). The imprints of all right and left-hand fingers were taken, and the types of the fingerprints were determined using a standard protocol. The blood group of all the subjects was recorded. Chi-square test was performed to identify the association between the fingerprint patterns and the ABO and Rh blood groups.FindingsThe loop fingerprint pattern was the most common in Omani subjects (49.4%), followed by whorl (44.9%) and arch (5.7%) pattern. A significant association (p < 0.001) was found between gender and fingerprint pattern. The loop was the highest occurring pattern in the females (54.6%), while the whorl was more in males (50.0%). The whorl pattern was the most common in the AB+ and O− groups. The loop was a predominant pattern in the A+, A−, B+, B− and O+ groups. The Chi-square test also revealed a significant correlation between different fingerprint patterns and blood groups of the subjects (p < 0.001).Originality/valueThe present study is an outcome of undergraduate student's research project thesis for the Doctor of Medicine (MD) program. The results of the present study may help in creating a data bank for biometrics, which can be useful for diagnosing associated diseases and also help in identification of individuals.

Relationship between dermatoglyphics and blood group of male and female first-year medical students at Rama Medical College, Kanpur

“…The results of a study conducted on Omani population suggested that the predominant fingerprint pattern among their study population was loop (49.4%), followed by whorl (44.9%) and then arch (5.7%) pattern. 14 Similar results were documented by majority of other studies from different parts of the world. The loop was the most common pattern observed in a study by Patil et.…”

Study on Inheritance of Fingerprint Pattern and its Association with ABO Blood Groups at Nagaon, Assam

“…Tarik Al Habsi along with his team studied the association between fingerprints and blood groups in the Omani population and found that loop fingerprint pattern was the most common in Omani subjects (49.4%), followed by whorl (44.9%) and arch (5.7%) pattern, loop occurring more in females than in males and the test also revealed a significant correlation between different fingerprint patterns and blood groups of the subjects but never mentioned about their inheritances relationship (10) .…”
