The sheep they cloned, Dolly, did die earlyer but to elaborate on this comment it wasn't "health issues" it was the length of the telomeres on the chromosomes that was the problem. Telomeres are the disposable buffers that disintegrates as we progress through life. Once our telomeres are gone, our DNA slowly disintegrates (in a nut shell ) When the sheep was cloned, the clone recieved chromosomes that were already missing a large portion of the telomeres because the cloning took place later in the sheep's life. It would have been fine had the sheep been cloned as a baby.Originally Posted by Gaz
Oh and Darkonix, i believe the cell's u are refering to are the stem cells. And they can get these from bone marrow and from an umbilical cord now. Neither of these process require you to destroy and embrio.
