Sex Identification in Fresh Blood and Dried Bloodstains by a Nonisotopic Deoxyribonucleic Acid (DNA) Analyzing Technique

Abstract
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 patt
