These peculiar traits which make a person stand out from the rest of the population are of exceptional significance in the arena of law and criminal justice. Identifying any person by his/her physical feature is very easy and the characteristics are observable to any human eye. But there may be cases were looks could be deceptive and physical traits could be fallible, as in case of twins. Twins have been studied ardently for decades now to introspect the role of nature and nurture in humans varied number of times in behavioral sciences. Twins, specifically Monozygotic Twins have been believed to share closely similar DNA and this makes a ground for an interesting piece of work as the genetic make is expected to be more or less the same. The present study aims to understand if the principle of similarity observable in twin characteristic extends even to one of the most unique identification feature in humans, the fingerprints. The samples chosen here were 20 pairs of Twins (10 of each identical and fraternal twins). The study area was restricted to Dharwad District of Karnataka. The observations made were that monozygotic twins had 84% of the times similar basic pattern (arch, whorl, loop, composite) on the same finger as opposed to fraternal twins who had a recurrence rate of 53% of the times, Although the intricate ridge patterns (ridge endings, bifurcations etc) differed even in cases where the basic patterns were the same. The tools and techniques used for collection and studying the prints were traditional manual methods and no biometric tools were made use of. | | Keywords : | | |
