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.

动物真的可以克隆吗？我想克隆我的狗。

动物克隆确实存在，但是，宠物克隆现在还没有。估计以后也不会有。

为什么不呢？我觉得有不少人想克隆宠物吧？

因为你得考虑这样一个问题：克隆并非复制。克隆者是一个独立的生物个体。狗狗先生的克隆产物和它本身唯一的共同点在于基因序列。

只是基因序列吗？不是所有的都相同？

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。

报告显示克隆猪和正常繁殖的猪并无二致，都存在生物变异。有的鬃毛较多，有的没有鬃毛。有的牙齿更多，有的牙齿更少。

克隆的宠物至少保留了讨人喜欢的个性吧？

可能会哦！同是得州农工大学的Duane Kraemer研究出了世界上第一只克隆猫。克隆猫的性情和原来那只猫的性情大不同——友善了不少。
