Sorry, I can't go back and edit my post--the time limit has expired.
Optimal Selection does NOT check for genetic diseases. It is purely for checking optimal matings for different breeding pairs in its database. Sorry about that!!!! The link to the diseases on different chromosomes was purely for information purposes, as far as I can tell

. The Royal Canin test DOES purport to test for 13 diseases, with more added over time, but you will have to check with your vet for the latest information on that.
