MB: Xiao Qing, do you think cloning is cruel?,XQ: What do you mean by that? The scientists are doing a wonderful job and soon they may be able to bring back extinct animals or ever peoples favourite pets back to life. MB: Yes, Qing, I know. But doesnt that seem strange to you? Is it worth it? It took 276 experiments before,Dolly was successfully cloned. Think of all those live cells and eggs that died in order for Dolly to be born. I dont approve of that! XQ: But Mary, be reasonable. Isnt it always like that with a new science? This is the way you learn to do,things better. Its just that this one deals with living things. MB: I suppose so but they make the animals do unnatural things. One poor cow was made to give birth to a bison. What was the poor creature to think when is saw its baby?,XQ: I dont quite understand why so many people are against cloning. I think the scientists need a little encouragement. They have done some amazing things and think of the benefits. Producing animals that are an exact copy of the original may help medical science produce,medicines or even organs for serious illnesses. MB: Yes, Ive heard all that. I agree with it but I dont agree with the methods. I dont think cloning is good for animals. XQ: Why not?,MB: Well, I think its a dead end. Dolly the sheep was “middle-aged” when she was born because her DNA came from a middle-aged “mother”. Cloning your grandmother would mean the new baby started life as an old lady!,XQ: Are you sure? I never thought of that! MB: And it also weakens the species. Clones mean there is less variety in the species and so illnesses will become more common and the animals may die out.,XQ: Oh dear!

But how could this possible happen? CP: Well, the scientists may get confused. WQ: My goodness. Surely they would notice if there is an age-gap,between the donor
