__ Therapeutic cloning and reproductive cloning __
Therapeutic cloning || Reproductive cloning || Similarities · Both aren’t ethically passable, because the embryo will be killed ||
 * * In-vitro (=in a test tube) || * In-vivo (=in a living organism) ||

__ Advantages and Disadvantages __
Pros || Cons  || Cures diseases and disorders || Ethnical problem, because embryos were killed to gain stem cells || Replace diseased new body parts || It’s expensive || Also heal [|neuropathies] like Alzheimer || || = How it works = This stage of development is called a blastocyst, this process destroys the embryo
 * collect eggs from women's ovaries
 * removed the genetic material from these eggs with a needle
 * A skin cell was inserted inside the enucleated egg to serve as a new nucleus
 * Stem cells are extracted from the egg after it has divided for 5 days.
