Ian Wilmut, the British scientist who led the team that cloned Dolly, points out that cloning is presently “a very inefficient procedure, ” producing a death rate among fetuses that is about ten times higher than in natural reproduction.
Briti teadlane ja Dolly klooninud rühma juht Ian Wilmut ütleb, et kloonimine on praegu „väga saamatu protseduur ”, mille tõttu nende loodete suremus on kümme korda suurem kui loomulikul teel sigitatud loodete suremus.
