Samson is a well‐bred, accomplished German shepherd dog whose owner was approached by a friend who wanted to breed his very nice female German shepherd dog to Samson. Although Samson had quality hip conformation, Samson's uncle had poor hip conformation, so Samson's owner studied the OFA health registry for the health clearances of the female. The potential dam, and all her relatives, had good‐quality hip conformation. Samson's owner agreed to the breeding because the risk of hip dysplasia in the offspring was very low and in fact, the puppies all had good hip conformation at adulthood.

The owner of Benji, a Bengal cat, read about progressive retinal atrophy in the breed, an autosomal recessive disease that causes blindness. Both carriers and homozygous normal cats will have normal vision; only if the Bengal is homozygous for the progressive retinal atrophy‐b mutation will it be blind. The genetic mutation test revealed that Benji was a carrier. Benji's owner was relieved that the cat would not go blind. Furthermore, the test results were submitted to the genetic health registry and future and current Bengal cat owners could use that information in their own decisions.
