Identical twins were assumed to share the majority of their characteristics. Dermatoglyphics is the scientific study of fingerprints (from ancient Greek derma=skin, glyph=carving). The ridges and groves on the palms and soles are distinct and are influenced by DNA. Between the 10th and 17th weeks of pregnancy, palmar and finger dermatoglyphics arise, and their morphology can be altered by genetic or environmental factors, interfering with normal intrauterine development. The purpose of this study is to evaluate the dermatoglyphic patterns in monozygotic and dizygotic twins, as well as the amount to which they share. The fingerprint patterns were analysed from the photos acquired after gaining informed verbal consent from three pairs of twins. Two sets of dizygotic twins (one set of females and one set of males) and one set of monozygotic twins (females) produced the following results: 1st pair-: The designs on the left hand did not match at all, but three fingers on the same hand do. 2nd pair-: The dermatoglyphics of two right-hand fingers and three left-hand digits were identical. The remaining digits did not have the same pattern. 3rd pair-: Dizygotic males were found to have the same pattern of two digits on the left hand, but no digits on the right hand. The patterns were discovered to be identical on a few digits but distinct on the others, according to the current study. A higher number of twins might be evaluated in this study, which would improve it.
