Study of Fingerprint Patterns in Relation to Gender and ABO Blood Groups

Abstract

Fingerprints are considered as the best tool of identification of a person. Fingerprint evidence is by far the mosteffective and reliable evidence in the court of law. The reason being fingerprint pattern persist same throughoutthe life and no two individual has similar pattern. Both blood group and dermatoglyphic pattern have geneticinheritance so an attempt has been made to analyze their correlation with gender and blood group of an individual.The objective of the study was to determine correlation (if any) between the fingerprint pattern, blood group andgender. The study was conducted on 150 students (88 males and 62 females) in the age group of 18-25 years.The fingerprint pattern of the study participants was compared with the gender and ABO-Rh blood group aftertaking their Informed written consent. Amongst ABO blood group, the most common blood group was O (40%),followed by B (35.33%), A (19.33%) and AB (5.34%). Rh + ve was the most common rhesus factor (97.33%). The loopwas the most common pattern (69.14%), followed by whorl (26.06%) and arch (4.80%). Frequency of loops werehighest in both the Rh-positive and Rh- negative subjects of ABO blood groups except O -ve blood group wherewhorls dominate. Loops are maximum seen in blood group B while whorls are more common in blood groupO and arches with blood group A. The present study confirms that loop is the most common type of fingerprintpattern while arch was the least common. The study revealed significant association between the Fingerprintpattern, Gender and ABO blood group.
