| Abstract | | Dactylography is considered as an unequivocal tool for identification and along with blood grouping and
matching remains an essential part of crime investigations. The present research evaluates the dermatoglyphic features
in different blood groups and to studies the relation between fingerprint patterns and blood groups. The study was
conducted on 110 students of Indian origin. The participants were explained about the procedure and rolled fingerprints
were taken for all the fingers using standard techniques. Thus, a total of 1,100 fingerprints were obtained. ABO and Rh
blood groups were recorded from each participant. The details of fingerprint patterns observed for each digit were
entered in a datasheet and analysed using SPSS version 16.0. Pattern Intensity Index was calculated for the quantitative
analysis of the fingerprint patterns. Chi-square test, one way ANOVA and student’s t-test were performed to compare
the variables included in the study. P-value <0.05 was considered as statistically significant. Loops were the most
frequently observed pattern in each of the four blood groups followed by whorls and arches. However, the relative/
proportionate distribution of fingerprint patterns varied for each blood group among males, females and total sample.
The differences in the overall frequencies of fingerprint patterns in different blood groups were observed to be
statistically significant among males (χ2 = 19.42, P = 0.004), females (χ2 = 20.63, P = 0.002), and the total sample
(χ2 = 17.75, P = 0.007). No statistically significant differences were observed for the Pattern Intensity Index among
different blood groups in males, females and total sample. It is recommended that the association between blood groups
and fingerprint patterns is studied on a larger sample, and in specific population groups. Apart from helping in forensic
and crime scene investigations, association of fingerprint patterns and blood groups can be of interest to human
biologists and physical anthropologists. | | | | Keywords | | Human biology – Dermatoglyphics – Fingerprint patterns – Blood groups | | |
