Controversial Debate

Types of Cloning Embryo Cloning Reproductive Cloning Therapeutic Cloning Replacement Cloning

Embryo Cloning Identical twins are produced Identical DNA. Used on various animal species Limited experimentation on humans.

Reproductive Cloning Produces a duplicate of an existing person. Animals are born with severe genetic defects. Basis of agrument that this is anunethical procedure It is specifically banned in many countries. Rumors that a successful pregnancy by the controversial Italian embryologist, Dr Severino Antinori.

Therapeutic Cloning Similar to reproductive cloning, but the stem cells are extracted from the pre-embryo, with the intention of generating a whole organ or tissue, so that it can be transplanted back into the person who gave the DNA. Death of pre-embryo Goal: create a healthy organ or tissue of a sick person

Pre Embryo a human embryo or fertilized ovum in the first fourteen days after fertilization, before implantation in the uterus has occurred.
