Person gets a dog, this dog is a very strong linebreeding - the dogs behind this dog meight not have the same name, but are bred back on the same lines ...

Sonia Dobe wrote:3.Theoretical linebreedings in fact are inbreedings in most cases. For instance puppies with a Wright inbreeding coefficient F=6.25% in a 4 generations pedigree (consanguinity 3-2 on a very inbreed popular sire), can be F=16.76% and a kinship coefficient R=30.9% in a 15 generations pedigree!
