Clear Carrier Affected explained.
The chart shows potential outcomes of breeding with DNA results from Clear, Carrier and Affected parents.
Clear : This finding indicates that the gene is not present in the dog.
Therefore, when used for breeding, a clear dog will not pass on the disease/trait to offspring.
Carrier : This finding indicates that one of the disease/trait gene is present.
The dog will not exhibit any symptoms of the disease and will not have medical problems as a result. If used for breeding, even to a dog with 'clear' status, theoredically 50% of the offspring will be 'carriers'.
Affected : This finding indicates two copies of the disease/trait in the dog.
The dog will be medically affected and show signs of the disease or trait.
Breeding with 'affected' dogs is not recommended.

It's always best to breed 'clear' to 'clear'.
If followed by all Breeders it will ensure a reduction in the frequency of the unwanted disease/trait in future generations. However, to retain a larger gene pool 'carriers' may be used in breeding programs provided they are bred with 'clear' partners.
Note : By using 'carriers' even to clear partners potentially 50% of the offspring will also be 'carriers'. Over time the disease/trait may be passed on for many generations through 'carriers' making 'clear' partners harder to find.
