@gbroxon:
Once again, my ignorance showing-blushes-a male can be affected and still be bred to a clear bitch? The progeny will test as clear? It's not the same for an affected bitch? Or is it just too dangerous for an affected bitch to be bred?
With regard to the irresponsible breeder thing, I really wasn't thinking of them testing (good gosh, that'd cut into their profit margin!), but of them somehow getting ahold of, say, a male carrier and a female carrier and breeding them, introducing (I think) at least the possibility of an affected, thereby negating the careful breeding of clears to carriers in those lines and re-introducing [an instance of] Fanconi into the breed that could extrapolate exponentially.
Do you think the breed can ever be free of at least the threat of Fanconi? Although (obviously), I know nothing of genetics, it seems like the only way to completely obliterate it would be to only breed clear to clear, and that can't be possible with the small Basenji gene pool(?).
Yes, affected males could be bred to clear bitches, know however that all pups will be carriers so then those must also be bred to clears…
It is NOT necessary to only breed clear to clear, that will really hurt the gene pool and put us in the same position that happened with HA which is also a recessive gene... you can safely breed Carrier to Clear, test the offspring to see what is clear and what is not. What not to ever breed is Carrier to Carrier, Affected to Carrier. As far as breeding affected bitches, IMO it is too much strain on the body to take that chance.... even if they are not yet expressing Fanconi. It is possible to breed out Fanconi, but only with careful breeding and not by throwing the baby out with the bath water...
Regarding "back yard breeders" and puppy mills breeding affected and/or carriers back into the gene pool, that will happen as they will never test.. the course of action is to educate the public on were to buy a puppy.. (and this goes for any breed) ....
