Can someone please tell me what the expected results of Fanconi tests on puppies born to TWO affected parents would be?? Could there be CARRIERS as well as AFFECTED??
Also, what combination of results on parents would produce Clear, Carrier AND Affected puppies in the same litter?? Would one parent have to be affected and the other clear??
Affected to Affected = All Affected - Should never be done
Affected to Carrier = 50% chance of Affected - Should never be done
Carrier to Carrier = 25% chance of Affected - Should never be done, as there is never a good reason to have a chance of an Affected
Clear to Affected = All Carriers, this is an acceptable breeding (provide the breeder is responsible in placement of the pups so that they are not bred to Carriers/Affected)
Here is another link explaining.
