Epigenetic approach to the analysis of formation of finger prints patterns and their population distribution

Guseva I.S.

Abstract

Skin crests are formed as a result of epigenetic way of development in embryogenesis, which exists in phylogenesis and is inherited by humans from higher primates. Formation of patterns depends on the degree of swelling of the subunguis, which is associated with proliferative activity of germinal epidermis layer and water saturation of derma. Ulnar-radial direction of the pattern depends to some extent on the specificity of finger blood supply. Primary morphogenetic indicators are the type of the pattern, ridge width and the distance from the highest point of subunguis to its base; secondary – delta and ridge count. Specificity of phenogenesis is defined by such population characteristics as pattern expressivity, their carrying and total phenotype.
