Relationship between finger print patterns with blood group and genotype among basic medical science, students of Bayero University, Kano

Abstract

Fingerprint patterns and the blood genotypes of individuals are chiefly determined by genetic factors during in-utero development. Evaluating genotypes requires expertise and facilities which could relatively be difficult to obtain and operate in some setting. The aim of the current study was to determine the correlation between hand finger print patterns and the common blood typing phenotype (genotype and blood group) among agroup of consenting adult population in Nigeria. Four hundred students (217 males and 183 females) of the Faculty of Basic Medical Sciences in Bayero University Kano had their total hand fingerprints captured using a scanner / computer set up. Data regarding common blood phenotypes was also determined for all participants from the blood phenotype information on their University identification cards. The mean age of theparticipants was 21.86±3.37 years. Loop finger prints patternwas the most common identified in the participants (58.4%), followed by whorls (27.9%), and then the least was arches (13.7%). There was a significant association between the finger print patternon the left thumb (p=0.012) as well as right thumb (p=0.013) withblood groups, while the print in the right index (p=0.042) and left little finger (p= 0.024) were associated with genotypes in the participants respectively. There was a relationship between the finger prints patterns the thumb, index finger and little finger with the common blood typing phenotypes. Thus, finger print patterns on the right index and left little fingercorrelates with blood genotypes.
