For example, if we only test one dog, and thus have no means to differentiate between the parents, we assign each parent the same probabilities of being clear, carrier, affected based on what the dog we tested came out. For example, if we start with only one puppy from a sire x dam being tested we cant really differentiate the probabilities between the sire and dam. You can post now and register later.
