XQ: Really? I 17 never thought of that.
RB: And it weakens the species. Cloning means that there’s less variety in the species. So the animals may not be able to resist..kki a particular illness and they might 18 die out.
RB: Yes, I know and I agree with that. It’s just that I don’t agree with the methods.
XQ: Why not?
RB: Well, I think it’s a dead 13end. Dolly the sheep was “middle-aged” when she was born 14because her DNA came from a middle-aged “mother”. 15 Cloning your grandmother would mean a new baby started life as an 16 old lady!
