Through the example of the distribution of PCR products in DNA matrices of
mouse tail tissue, a method of comparative analysis of DNA fingerprints is
described. The PCR products were obtained using a 20-mer random primer flan
king the Atp1b2 locus on mouse chromosome 11. A software program was design
ed that permits the simplification of comparison of DNA fragments variabili
ty or polymorphism detected on electrophoregrams from different individuals
.
