THE GENETIC SELECTION ISSUE. .
Modernscience has proven that most of the diseases that exist today are hereditary. In other words, these diseases are found in the genes of individuals and are passed from one generation to the next. Forthis reason, many scientists have been working for over ten years on techniques and treatments such as Inheritable Genetic Modification (IGM) and Genetic Selection (PGD), techniques through which thegenes that are passed to future generations can be changed, allowing couples with risk of passing serious disease to have healthy children. As genetic investigations go forward there is more hope forimprovement on human health, but at the same time it leads to a controversy on the ethical barriers. Are the benefits of human health the real use that science would give to such incredible innovationsin biotechnology, or would these innovations open the door for new experiments like trying to create super-humans?
IGM is a complicated scientific technique which allows scientists to modify anindividual’s genetic sequence so that the disease will never occur in the first place. It is supported by many people and families who have had children with hereditary diseases and who want to have morechildren, but are afraid to pass diseases to their future children and who want to help the older children. Thanks to this new method, organs and tissues can be transplanted through “savior siblings” tosick, older siblings in order to save their lives.
In addition, other people support IGM for the fact that the genetic selection will allow couples to “improve” their child’s health, athleticism,attractiveness and intelligence to have the qualities that everybody wants for their children.
Some scientists are also in favor of IGM because they believe that to administer a chemical substance,...
