Pig clones cloned, cloned and cloned again

Piglet clones

Aaah, aren’t these little piglets cute? They’re also fourth-generation piglet clones, apparently free of any abnormalities resulting from their engineered origin. Scientists have pinned great hopes on the cloning of animals as a potential solution to the world-wide shortage of transplantable organs; pigs, with their great similarity to human physiology, may well play a large part in such plans.
