You're not clear if you mean sheep or humans.
Obviously, lots of Christians are OK with sheep cloning. Obviously, some are not.
Orthodox Jews might think it's wrong, but Reform, who are the majority, probably don't have a problem with sheep being cloned. It is ultimately up to each individual to decide.
Orthodox Jews are probably against human cloning. Reform probably believe we are not yet ready for it, but probably think it's inevitable, and not really so bad because indentical twins are essentially clones.
