What is inheritable genetic modification?
IGM refers to the technology of changing the genes that are passed on to the next generations of the human species. The genetic alterations would be made in sperm, eggs, or early embryos. Engineered genes would appear in the person who was formed from that embryo or gamete, as well as in the future generations. This technique has not been tested in humans. IGM would be without a doubt the most important, but also most controversial, type of genetic engineering since it would irreversibly modify the human species. What are the arguments in favor of IGM? Proponents of IGM argue that this technique can be used to enable people to avoid passing on to the future generations such serious genetic diseases as Tay-Sachs. It can also allow a couple (both are homozygous for a flawed gene) to conceive a healthy baby related to both of them. In addition, IGM can allow people to genetically “enhance” their babies to live longer, become healthier, more attractive, more intelligent, and more athletic.
