RESUMO
True cloning is fission, budding or other types of asexual reproduction. In humans it occurs in monozygote twinning. This type of cloning is ethically and religiously good. Human cloning can be performed by twinning (TWClo) or nuclear transfer (NTClo). Both methods need a zygote or a nuclear transferred cell, obtained in vitro (IVTec). They are under the IVTec ethics. IVTecs use humans (zygotes, embryos) as drugs or things; increase the risk of malformations; increase development and size of abnormalities and may cause long-term changes. Cloning for preserving extinct (or almost extinct) animals or humans when sexual reproduction is not possible is ethically valid. The previous selection of a phenotype in human cloning violates some ethical principles. NTClo for reproductive or therapeutic purposes is dangerous since it increases the risk for nucleotide or chromosome mutations, de-programming or re-programming errors, aging or malignancy of the embryo cells thus obtained.
