Genetic engineering, also called genetic recombination, or gene grafts. Is a synthetic approach, synthesis of a healthy, normal, with no disease genes, to pathogenic gene replacement in patients with genetic diseases, to improve the genetic quality of the human. In the \"in vitro\" after fertilization, eugenics purposes can be achieved of selected and interference and control of certain genetic disease genes grafted gene into fertilized eggs, embryos-inheritance of genetic traits and their descendants have changed.
However, these ideas are now limited to in a laboratory test, is only in the success of the microorganism in the lower reaches, only a little clues in the higher organisms, as regards application in humans is a vision.
If the grafted gene can succeed in the future, when human fertilization, embryogenesis and cell differentiation, becomes a manual process. In this way, some genetic diseases in humans eliminate, and also opened the road to a new eugenics.
Exploration of these change human genetic qualities, at present there is some scientific attempts. We believe that humans might be the very first time on reproductive and genetic to achieve the aspirations of eugenics.
Evolution of positive eugenics, also known as eugenics, these had achieved some results in varying degrees in several areas, these are very remarkable. However, because it involves human society existing on a variety of ethical, moral, legal futures studies on many of the problems, differences and debate in the academic community there has always been greater. Therefore, should further improve and supplement human reproductive technology in clinical applications, research requirements, to reduce the unnecessary adverse to modern and future generations, so as to really achieve the objective of improving the quality of human.
