If a Dexter owner ever questions Why Parent Verification......
Taken from an article: Increasing Pedigree Accuracy with DNA Parent Verification - located here:

An interesting case study into how easily errors can occur in pedigree recording even in a herd following best practice guidelines, was demonstrated in the Beef Information Nucleus Progeny Test Program conducted by the Australian Limousin Breeders Society. To ensure accuracy of sire information, the sires for all calves from the first joining in 2011 were checked by DNA profiling and verification. The parentage verification highlighted a number of pedigree recording errors including:
• The wrong straw of semen was used or the sire recorded incorrectly for three calves during the AI program.
• Four calves were incorrectly assigned to the back up bull whereas they were actually sired by the AI sire.
• Human error occurred during the data entry for another three calves.
• Two calves born on the same day had clearly swapped mothers at birth.
In total, 12 of the 227 calves (5.3%) were given incorrect sires when the pedigree information was collected. Considering the Limousin Progeny Test Program was following best practice guidelines, it is probably indicative of the lower level of pedigree errors occurring across the registered cattle industry and highlights the benefit of DNA parentage verification.
