DM transmission: DM/DM x DM/DM = N/DM?

I wonder what's the statistical probability that a couple of dogs from the same kennel underwent the mutation?

Sure, other labs may also be accurate, but if you want OFFA scientists to answer any questions, you have to have the tests done through them, since they don't confirm others' results on their patented test.

But I agree that perhaps there's nothing for OFFA scientists to answer, that the problem is somewhere else (and not the tests nor the mode of inheritance).

I don´t know if Missouri was the first to invent a test and it is normal, that different research groups invent their own tests and sell them to commercial labs. As Bern University told me is the used test based on the gene research of a Swedish group.
I don´t know which test Prag is using.
Laboklin has the official permission to do rabies-titers for the import into the EU, what means, it is a lab that fits extremely high standarts and the work is controled on regular basis.
All results I know of fit the results of the parents, so if there is unregularity the right thing to do would be to contact the lab, ask them for their advise, do some paternity tests and - if paternity is positivly stated - let the tests be confirmed by another lab.
