Abstract
Four probes known to allow DNA fingerprinting in the human (M13, Jeffreys’ core sequence, the human α globin hypervariable region [HVR], and a mouse probe related to the Drosophila Per gene) were checked for their ability to reveal “genetic bar codes” in cattle, horses, pigs, dogs, chickens, and a European cyprinid fish, the barbel (Barbus barbus L.). Individual-specific patterns were obtained in cattle using M13, Jeffreys’ core sequence, and the α globin HVR, in horses, dogs, and pigs using M13, Jeffreys’ core sequence, and the Per probe, and in chicken and fish using the four different probes. Although we observed a considerable heterogeneity in the extent of interindividual variation, depending on the particular probe-species combination, the fingerprints are polymorphic enough to be used efficiently in animal identification, paternity testing, and as a source of genetic markers for linkage analysis. These markers should substantially accelerate the mapping of genes affecting economically important traits.
