[ID 45557] ESTUDO DATILOSCÓPICO ENTRE GÊMEOS MONOZIGÓTICOS PARA FINS DE IDENTIFICAÇÃO HUMANA

Abstract

Objective: To analyze dactyloscopy characteristics between MT pairs, observing coincidences and divergences between the siblings and evaluating the identification potential of the fingerprints for their individualization. Material and Methods: Blind and cross-secional, quantitative study with inductive approach and extensive direct observation. The fingerprints were analyzed and classified into patternal types (arch, internal clip, external clip, verticil and anomalous) and accidental (anomalous, scar and amputation) and, later, the characteristic points were pointed out. Results: 46 fingerprint records were collected from 23 MT pairs, of those 14 were female pairs and 9 male, with ages between 18 to 28 years. The fingers that showed the highest agreement among the MT pairs were the right and left thumbs, and the right ring finger with 82.5%. The right hand showed the external clip as the most frequent pattern, while the left hand the prevalent type was internal clip. Conclusion: The fingerprints’ components, although very similar, are able to individualize MT by the existence of individual characteristic points, supporting the process of human identification.
