Haploidization
During haploidization , the nucleus of an egg cell is removed and replaced by the nucleus of another cell in the body . If the egg cell prepared in this way is fertilized with a sperm , then half of the egg cell's chromosome set is split off as polar bodies and the formation of an embryo can begin.
With the help of this procedure one hopes for an advance in reproductive medicine . For example, gender- unspecific reproduction is basically possible. However, all previous attempts have not resulted in a viable embryo.
