Maybe not, but it turns out it may be a good thing, anyway. Pigs are used in all kinds of experiments, and cells from the green pigs, who carry genetic material from flourescent jellyfish, are easy to spot. So, as the BBC article states:
...if, for instance, some of its stem cells are injected into another animal, scientists can track how they develop without the need for a biopsy or invasive test.
The more you know, I guess. Let's just hope this mutation is safe for consumption, because then it could also solve the whole green pig penis doggy treat problem, too.
Update: Although they might not actually be green, pigs implanted with genes from spinach are supposed to be good for you - at least according to the nutty scientists who made them. So, next time you want to eat healthy, put down that salad and pick up some bacon!
