Are cloned animals more prone to diseases?

Myth: Cloning results in severely damaged animals that suffer, and continue to have health problems all their lives. The vast majority of swine and goat clones are born healthy, grow normally, and are no more susceptible to health problems than their non-clone counterparts.

Why do cloned animals have health problems?

Researchers have observed some adverse health effects in sheep and other mammals that have been cloned. These include an increase in birth size and a variety of defects in vital organs, such as the liver, brain and heart. Other consequences include premature aging and problems with the immune system.

Why do cloned animals have birth defects?

Scientists also knew that cloned animals had been born with a similar condition, called 'large offspring syndrome'. ... "This appears to be due to the abnormal gene expression we saw in the cloned group.

Why do cloned animals have the same DNA?

Clones contain identical sets of genetic material in the nucleus—the compartment that contains the chromosomes—of every cell in their bodies. Thus, cells from two clones have the same DNA and the same genes in their nuclei.
