[Applicability of the Jeffreys 33.15 and 33.6 multi-locus system].

A sample of 73 families which had been investigated by conventional paternity grouping was in addition subjected to DNA analysis using the multi locus systems 33.15 and 33.6. A comparison with the results of a conventional expert's opinion shows complete accordance. In cases showing exclusions in the conventional systems there were also exclusions by the multi locus systems and in cases without exclusions in the conventional systems no exclusions were found using multi locus probes. New mutations were not observed. In stain cases the resulting band patterns were often partially deficient. The problems in assigning such patterns with those observed in fresh samples are discussed.
