New possibilities for determining the sex and age group of an adult on the basis of the frequency analysis of combinations of dermatoglyphic signs of fingers

: The possibilities of determining the sex and age group of an adult on the basis of frequency analysis of combinations of dermatoglyphic signs are presented. The study established new, highly informative dermatoglyphic markers of general physiological traits, with a multiplicity of differences from 5 to 59 (p<0.05) in alternative comparison groups formed by sex and age groups of 18 to 35 years and 36 to 77 years. It was found that the combination of acquired signs of raised skin (white lines and scars) is more informative if compared to the combination of congenital signs (types of patterns, outlines of papillary ridges). Depending on the number of fingers studied, the total occurrence of informative combinations can be 37.8 - 64.4% (one finger) to 96.9% (5 fingers of one hand). The result opens up the prospect for the application of a dermatoglyphic research method in the identification of persons from fragmented human remains and fingerprints found at the scene of an accident.
