To reveal constitutional liability of children with mental retardation (MR), dactiloscopy was performed in 200 children with MR of a cerebral-organic genesis (129 boys and 61 girls), 110 normal children (56 boys and 54 girls) and 95 children with an undifferentiated form of oligophrenia at the stage of debility (68 boys and 27 girls). It was found that mentally retarded children as compared to normal children more frequently had a pattern of the "coil" type, dysplasia of the crest lines, less marked bimanual symmetry of patterns and less pronounced sex differences in the frequency of finger patterns.
