Cloning - Well, Split My Embryo!

Clone - Yes, I divided my embryo. Genetic engineering, which introduces genetic material of other organisms, changes the genetic characteristics of the organism in a predetermined manner. Once the problem of inefficient transfer of genetic material is overcome, genetic engineering can give hope to many hereditary diseases treatments. Another development is an improvement of the technique known as cloning, which produces a large number of genetically identical individuals by transplanting the whole cell nucleus.

Artificial embryo division or embryonic twinning is a technique for producing single elliptical twins from a single embryo, unlike other cloning methods. In this process, the donor embryo is divided into two different embryos and then transplanted by embryo transfer. It is optimally done in 6 to 8 cell stages that can be used as amplification of in vitro fertilization to increase the number of available embryos. If both embryos succeed, it will produce identical twins (identical twins).

Another simpler cloning method called embryo splitting or artificial twin sister was developed in the 1980's and used by livestock keepers. In the process, the early embryo is simply divided into individual cells and cell populations like twins, triplets, and other proliferation. Each cell or collection of cells grows into a new embryo that is then placed in the uterus of the host's mother and is brought to maturity. This technique allows the production of multiple clones but clones are not from adult animals with known characteristics but from embryos whose physical characteristics are not entirely known - It is a serious limitation for practical application. By the early 1990's, nuclear transplantation using embryonic cell division and embryonic cells has been used to clone many animals including mice, cows, pigs, rabbits and sheep.
