Cloning quickly gets you lots of 'ideal' off spring but you also get a 'reduced gene pod'- this means there are fewer different alleles in the population. I the population are all closely related and a new disease appears, they could all be wiped out.

There may be no allele in the population giving resistance to the disease.

But the study of animal clones could lead to a greater understanding of the development of the embryo and of age related disorders.

Cloning could also be used to help preserve endangered species.

It's possible that cloned animals might not be as healthy as normal ones e.g the sheep had arthritis, which tends to occur in older sheep.

Some people worry that humans might be cloned in the future. If it was allowed any success many follow many unsuccessful attempts e.g. children being born severely disabled.
