You know, if you're dealing with prenups or something. But what does having proof change? If you're just dating then "we don't trust each other" is a good reason to break to break up.
To add to what others have said, there are some rules about it too. So, yes you can make transgenic mice or whatever, you can't give genetic disease to cats and dogs. But, vets can report a mutation and the animal can be bred to maintain the mutation in a new colony. That's where the cat model for ML2 came from. The rules are looser for livestock, so there are some pig models that were made with genetic techniques.

Yes this is a great point.
