-Added two paragraphs to Cloning Endangered species. They were removed later.

Some studies have stated a large concern with lack of genetic diversity when cloning extinct species. A lack of genetic variability is unavoidable when reviving a species from a single strand of DNA, with the same set of alleles. This lack of genetic variability leads to a higher susceptibility to disease and reductions in fitness. Studies have shown that genetic diversity is already lowered in endangered species, and therefore cloning these animals to repopulate only serves to increase this lack of genetic diversity. Proliferation of disease will also result as an effect of low genetic diversity. Vulnerability to disease is a concern as the species will not have the same ability to undergo natural selection. A single disease has the potential to affect the entire revived population. [61]

Extinct and endangered species are more susceptible to mutations. Mutation is a concern whenever a species is being cloned. Cloning extinct species requires the use of incomplete DNA from a species that is already dead. Replication of this DNA would be required, increasing the probability of errors in the genetic code. Mutations are likely to cause fatalities before the cloned animal comes to term. If animals do happen to successfully come to term, a variety of abnormalities are likely to occur as a result of inappropriate epigenetic programming. [62]
