I think the comment about age (puppies under a year) can not be counted as accurate yet is because Fanconi is late onset, so if they were to develope Fanconi, it would not be know now. But not sure if that is what you are asking?
I think I said clearly his results are seemingly about TESTING results, not actual development. So his results are accurate for TESTING, which is what he was posting, which has nothing to do with the age of the animal tested but only if it shows expected outcomes based on the sire/dam.
Age only has to do with outcome, not what his chart/results were about (ie if the linkage test results for sire/dam match what the offspring linkage test RESULT (not if they actually develop the disease)). Not sure how to make that clearer.
