A conservation centre plans one adult-cell cloning run using body-cell nuclei from one rare antelope.
Each surrogate mother can receive one embryo.
| Quantity | Value |
|---|---|
| Time available for the cloning run | 35 hours |
| Egg cells receiving a body-cell nucleus each hour | 18 |
| Egg cells that develop into embryos | 40% |
| Surrogate mothers available | 260 |
| Transferred embryos that produce live young | 35% |
| Target number of live young | 85 |
Determine whether the conservation centre is expected to meet its target.

All the body-cell nuclei are taken from the same adult antelope. Explain why this could be a disadvantage if a new disease affects the cloned group.
