Is animal cloning for real? I want to have my cat cloned.
Well, animal cloning technology exists, but pet cloning isn’t quite there yet. And it may never be.
Why not? I could think lots of people could want to have copies of their pets.
That’s just a problem. A clone isn’t a copy. It’s a separate, individual organism. The only thing clone of Mr. Wolfs and Mr. Wolfs of themselves have in common is their genetic sequence.
The only thing? Isn’t that everything?
Apparently not! As cloning technology has improved, more and more evidence has come out of clones that don’t look alike or act alike. For example, Ted Friend and Greg Archer, both at Texas A & M, have cloned piglets.
They report that there is just as much variation in appearance among the clones as among the non-clones. Some have bristly coats, others not; some have more teeth, some fewer.
But wouldn’t a clone of Mr. Wolf at least have its charming personality?
Maybe not. The world’s first cloned cat was made by Duane Kraemer, also at Texas A & M. He reports that the clone has a different personality altogether than its clone mother–it’s much more friendly, in fact.
当然不是！随着克隆科技的不断发展，越来越多的证明显示克隆并非看起来一样或行为一样。比如，德州农工大学的Ted Friend 和Greg Archer教授克隆了一批小猪。
