FEATURES OF PALMAR DERMATOGLYPHICS OF MEN AND WOMEN OF DIFFERENT GROWTH GROUPS
The article is devoted to the study of the relationship of unchanging and changing dermatoglyphic signs of the palms with the length of the adult body, taking into account its gender. Study material: dermatoglyphic maps of the palms of 208 men and 102 women aged 17 to 83 years (Central Caucasians). Research methods: obtaining palm prints using black printing ink on white paper by impression, recognition of dermatoglyphic signs by the method of H. Cummins, Ch. Midlo (1943), descriptive mathematical and statistical characterization of dermatoglyphic features, correlation analysis. It was found that the tall ones (from 180 cm) are characterized by positive patterning in the tenar region and in the II interdigital pad, as well as the presence of a proximal or distal axial triradius. In contrast, the undersized (up to 160 cm) are characterized by negative patterning and the presence of an intermediate axial triradius. The multiplicity of the difference in the frequency of occurrence of qualitative signs in different growth groups is from 2 to 5 (p<0.05). Among the quantitative features, the largest correlation with body length is the size of the palm print (0.66), the density of papillary ridges (-0.30) and the crest score (0.24). The relationship between the dermatoglyphic features of the palms and the length of the adult body is observed in both changing (linear size, density of crests) and unchanging features (pattern type, axial triradius, crest count), which confirms the multifactorial nature of the studied personality property and explains the difficulties faced by scientists-developers when creating expert methods for determining human height based on a limited set of features. It is concluded that high-precision diagnostic techniques can be obtained only if all groups of dermatoglyphic signs are taken into account.
