Is animal cloning for real？ I want to have my dog cloned.
Well， animal cloning technology exists， but pet cloning isnt quite there yet. And it may never be.
Why not？ I could think lots of people could want to have copies of their pets.
Thats just a problem： a clone isnt a copy. Its a separate， individual organism. The only thing clone of Mr. Dogs and Mr. Dogs of themselves have in common is their genetic sequence.
The only thing？ Isnt that everything？
Apparently not！ As cloning technology has improved， more and more evidence has come out of clones that dont 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 wouldnt a clone at least have its charming personality？
Maybe. The worlds 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–its much more friendly， in fact.
当然不是！随着克隆科技的不断发展，越来越多的证据显示克隆并非看起来一样或行为一样。比如，得州农工大学的Ted Friend 和Greg Archer教授克隆了一批小猪。
