of a greyhound that was dysplastic. However, 
there is such a wonderful selection against hip 
dysplasia in the greyhound. They are a very 
biased breed, because if they don't win at the 
stakes, they're put on the table. They are not 
frequently bred as pets. Therefore, any grey- 
hound with the slightest trace of these genes 
have no opportunity to breed. But it is there, I'm 
sure. I have heard rumors from other people, 
but I'd say any breed in which dogs grow to 
weigh around forty pounds or more will have it. 
And those that get larger, have it worse. We 
have shown quite clearly in our colony that the 
more rapidly growing, robust dogs have the 
worst hips. 
C. Stormont, School of Veterinary Medicine, 
Davis, California: I think this is a very good 
project like you said, Dr. Templeton, but the 
objective of selection is for adaptability. It 
seems to me this has it all over these long-term 
in-breeding projects. I know some that are and 
have been going on and have cost millions of 
dollars, and they're not getting any place. You 
have an objective. You can select your histo- 
compatibility and once you've got it reasonably 
well fixed in your dog colony, this should be an 
excellent dog for all kinds of transplantation 
procedures. 
Dr. Templeton : I think that if you need uni- 
form dogs they will be supplied by this breeding 
plan and you can also provide dogs defined in the 
genetics of histocompatibility.
