[Classification of blood stains inside a car using molecular genetic methods].

Sex-determination of a 1-year old blood-stain was realited by Dot-blot-Hybridisierung. The bloodstains were inside of a car. It was not clear, if the origin is female or male. By using total human DNA-probe (A) and a sex-specific DNA-probe (Y), (pJA 1143), labeled with P32, as soon as the calculation of the sex-specific quotient (A/Y) you could show, the bloodstains must be descended from a man.
