On the other hand, Dolly the sheep's chromosomes had shorter telomere lengths than normal. This means that Dolly's cells were aging faster than the cells from a normal sheep.

ScienCsts call this "Large Offspring Syndrome" (LOS). Clones with LOS have abnormally large organs. This can lead to breathing, blood flow and other problems. ScienCsts have mated male and female mice with large offspring syndrome and Observe that the progeny of these mice do no suffer from the syndrome Have humans been cloned? Despite several highly publicized claims, human cloning sCll appears to be ficCon. There currently is no s...
