Abstract
ackground: The identification of individual is important for both legal and humanitarian reasons. It is of
great importance because every individual exists as an entity in a society and is dealt with as such by the
legal system. The most commonly used method for identification is fingerprinting which relies on the
uniqueness of ridges present on thumbs and fingers. These are unique in arrangements and remain constant
throughout an individual’s life. Fingerprints of no two individuals are same even if they are twins. The power of
discrimination of the basis of fingerprinting is about one in 64 billion. The study was designed to carry out analysis
of fingerprints from mono and dizygotic twins and to differentiate them on the basis of fingerprinting.
Methods: This was a prospective cross-sectional study carried out among 30 pairs of twins including 17 pair of
monozygotic twins and 13 pair of dizygotic twins. After taking an informed expressed consent, the participants
were asked to press their individual fingers on the stamp pad. They were asked to then put and roll the stamped
finger onto an A4 size paper on which blocks for each finger were already made. Both left and right hands were
fingerprinted and with the help of magnifying glass, different types were identified including Arches, Composite
type, Loops and Whorls. SPSS software was used for data analysis.
Results: There was 7.6% of Arch type, 6.1% of tented arches, 1.5% of plain arches, 62.32% of loops, 6.66% of
double loop, and 3.83% of central pocket loop, 44.83% of ulnar loop, 7% of radial loop, 0.83% of accidental loop,
29.93% of whorls, 9% of plain whorl and 20.1% of central the pocket whorl.
Conclusion: When the left and right thumbs are compared with each other using eight (8) points, there are
matches on the first six (6) points, matching percentage for each of these pairs of fingers is 75%. But when the
both fingers were rotated on 180° and compared, the matching percentage was 87.5%. These 8 points
fingerprinting can be used to distinguish twins.
