Have to respectively disagree here folks, everything I have read and our breeding experience suggests polygenic in nature with both sides contributing but is only "exhibited" in males. I would love to read a study to the contrary, if you have one point me too it. Don't get me wrong, would love to put this all on the bitches, I just don't think thats the case, takes two to tango on this one, so to speak. ;-) I have run into Stud Dog's that have never produced a cryptorchid. And have used them with bitches that have in previous litters, the result has been litters with complete sets of testicles. The hiddn part of course would suggest that at 1/2 of these progent are carriers of the recessives or defective genes from the mothers side..
