Quizplus · Accepted Answer

Dolly, the cloned sheep, had shorter telomeres than her counterparts who were biologically conceived. This is likely due to the fact that her cells were derived from cells that were already mature and therefore had already undergone several rounds of cell division. Each round of cell division shortens telomeres, so cells derived from a mature animal would have shortened telomeres.
