Abstract

Summary. A multi‐locus DNA probe, R18.1, derived from a bovine genomic library, detected DNA fingerprints of highly polymorphic loci in hybridization to genomic DNA from poultry and sheep, and of moderate polymorphic loci in cattle and human DNA. The average numbers of detected bands in chickens and sheep were 27.8 and 21.4, and the average band sharing levels were 0.25 and 0.33, respectively. In hybridization to cattle and human DNA, the results were less polymorphic; nevertheless, individual identification is feasible using probe R18.1. The results obtained by R18.1 were compared to results obtained by Jeffreys minisatellite probe 33.6 and two microsatellite oligonucleotides, (GT)12 and (GTG)5. The total number of detected loci using probes R18.1 and 33.6 were estimated in chickens through family analysis of broilers and the maximal number of detectable loci was calculated.
