Why does OptiGen NOT certify pups classified as Normal by Parentage?
Theoretically, it would be correct to expect all descendents from a normal x normal mating to be normal for that exact genetic disease. This is true if both parents in EVERY mating are known to be genetically normal either by genetic testing or by “normal by parentage”. However, in order to confidently rely on this approach, you need to consider the requirements and risks: You must start out testing all of your breeding stock and any new breeding stock brought into your kennel. You must not rely on anyone’s “word” that a dog is normal. You must confirm parentage relationships for every descendent on an ongoing basis through parentage analysis. There is a very real rate of mistakenly identified parents, typically sires. We must stress to you that cases of faulty parentage happen to the very best of breeders. Accidents happen. Double matings happen. You can rely on “normal by parentage” only if you document actual parentage. Some breed clubs and registering organizations consider ongoing
