Authors on the base of the material investigated in the Department of Forensic Medicine of Semmelweis Medical University discuss importance of anthropological investigations as a valuable, additional to serology test. In cases when neither blood-group tests nor anthropology provided evidence sufficient to formulate a conclusive opinion chromosomal studies are recommended. The surveying of 300 cases with the C-band/showed the thickening of the heterochromatic part of chromosomes 1, 9, 16, Y/and the occurrence of total and partial inversion. Examinations with Q-band have revealed the incidence of chromosomal polymorphism.
