Abstrakt: Deoxyribonucleic acid (DNA) specimens were prepared from blood or bloodstain extracts, and the content of a Y-chromosome specific DNA fragment was investigated by the Southern hybridization method using a nonisotopic staining technique. Thus obtained patterns of male DNA showed a clear band, whereas broad stains with some faint bands appeared on the patterns of DNA from both sexes. This method is expected to be a new powerful mean of forensic medical examination.
