Dermatoglyphic Phenotype of a Person As One of the Criteria For Its Identification

Abstract

Introduction. One of the methods used to track the pattern of heredity and variability of human psychophenotypic traits is dermatoglyphic. It is used to study the hereditary patterns that form skin lines on the fingertips, palms, and soles of a person.
 The aim of the study to develop expert criteria for the informativeness of dermatoglyphic fingerprints in the system of forensic medical identification of a person.
 Materials and methods. The object of the study was fingerprint cards obtained from 460 people (200 women and 260 men) aged 18-59 years living in Ukraine. The dermatoglyphic method and the method of statistical analysis were used.
 Results. It has been established that dermatoglyphic features can be congenitally unchanged (pattern type and its orientation, comb and delta count, rudiments and dysplasias);
 congenital variables (altitude-latitude index, delta-interphalangeal fold distance, line density); acquired variables (white lines and scars).All these features have not only individual but also group variability.
 Conclusion. The proposed forensic classification of dermatoglyphic features does not include individual features of the structure of patterns (minutiae), the appearance of which is largely due to the action of random factors and therefore is valuable for forensic science (fingerprinting).
