As you say, but inserting genes from one animal into another that would never naturally have them is what is happening in this case. If they had a breeding program that achieved the same results I would be okay with that.

Because the actual number of total genetic combinations is a finite number, any combination you create in a lab, is possible in nature. Incredibly unlikely perhaps, but none the less possible. So you can't actually say that it would never occur.

Yeah, I know, I'm quibbling over the mathematics of infinity.
