Furthermore my essay will involve a look on cloning and sciene fiction and finish with the economic reasons for cloning humans.
My motivation to do the essay about this topic is not only that it is crucial for everybody to think about cloning but in my mind it is also very interesting and exciting to learn more about it.

Cloning is an asexual kind of reproduction. In order to understand the technique we first have to know how sexual reproduction basically works. The gametes have only half of the chromosomes a body cell has because during sexual reproduction the egg cell and the sperm cell come together and create a new life which then has a complete set of chromosomes 46 in every body cell again, 23 from the mother and 23 from the father.
If gametes would have complete chromosome sets, too, the number of chromosomes in the body cells of the following generations would continue to grow. Cloning works kind of similar but since the goal is to create something which is genetically identical to one model the fertilization process has to take place with the chromosomes the hereditary material of only one person or thing.

The fertilized egg cell then contains 46 chromosomes like it contains after sexual fertilization but with the difference that these 46 chromosomes are from one person and not from two, the man and the woman.
What happens with this fertilized egg cell next depends on what kind of cloning is to be practised, either therapeutic cloning or reproductive cloning.
When the cell has itself a few times divided, the valueable embryonic stem cells can be taken from the developing embryo, hereby the embryo is killed. These embryonic stem cells are so valueable because they can only be won from umbilical cord or from embryos and they are crucial for scientific research.
