Definition and types Cloning is the production of 1 or more individual
plants or animals (whole or in part) that are genetically identical to an original plant or animal.
I’ll discuss two types: (1) Reproductive cloning (aka adult DNA
cloning) (2) Therapeutic cloning (aka biomedical
cloning)
Reproductive cloning Produces a duplicate of an existing animal Dolly and the Raelians DNA from an ovum removed and replaced with
the DNA from a cell removed from an adult animal
The fertilized ovum (called a pre-embryo) implanted in a womb and allowed to develop into a new animal
Very controversial: banned in many countries
Therapeutic cloningInitial stages identical to reproductive cloningHowever, stem cells are removed from from the pre-embryo to produce tissue for a whole organ for transplant back into the person who supplied the DNA
