Are you saying that none of the dogs in my dog's pedigrees are in your dog's pedigrees? You don't have any Telvara, Homerbrent, Salador or Kindrum dogs in your dog's pedigrees? Polygenic traits are caused by a dog's GENOTYPE--the dog's ENTIRE genetic make-up--NOT just the approx. half of the genes that cause the dog's phenotype. Since half of those genes are not seen, we don't know what they are without looking further. The only way to figure out some of a dog's geneotype is to know as MUCH as we can about ALL the relatives as possible. If a dog develops MVD at age 8--that is that dog's PHENOTYPICAL expression of the approx. half the genes that dog inherited. There are still almost 50% of the genes that dog carries and can give to offspring for that trait that we don't know about. BUT, if you know when his grandparents, great-grandparents, siblings, aunts, uncles, cousins developed MVD you would have a MUCH better idea of what that dog's genotype. Say you were able to figure out there were 100 somewhat closely related dogs to your dog. If many of those dogs had their MVD status posted somewhere (when they developed MVD) and you found out that 90% of those posted had developed MVD by age 5--there would be NO surprise when considerably more than half that dog's offspring developed MVD by age 5--which was NOT your intention when you bred to him since HE was clear at age 8! Or vice-versa--if a dog developed MVD at age 5 1/2 and you got information on 100 of it's relatives and found out 90% of them were MVD clear till age 8 or 9--you wouldn't be surprised that most of hs offspring were clear considerably longer than that dog. There are no surprises when you breed genotypically--the surprises come because you are breeding phenotypically and not paying to the other half of those hidden genes. So the more information one has about all the related dogs in a pedigree, the more one knows about that dog's genotype and the better breeding decisions one can make for that dog. The status of ALL your dogs IS important to my breeding program!
