Do cloned animals have more health problems than other animals?
Not documented. It is true that an unusually high percentage of clone pregnancies are lost in utero. Most of these losses, at least in cattle, sheep and goats, can be primarily attributed to problems with the placenta’s attachment to the mother. It also appears that cloned offspring can have a difficult first 24-48 hours, during which time they appear diabetic. But this situation is not always observed in cloned offspring. However, if they do experience and overcome this difficulty, they appear to develop normally. Also, much more data has been reported indicating there is no “premature aging” in these animals.
