Since the Human Genome Project was completed, how humans can modify identified genes has become a hot topic. The analysis of DNA structure and gene locations makes the enhancement of artificial genes possible. Ethical and legal issues have been discussed around the world. Selecting a child's characteristics can be achieved by recombining DNA. The discovery of the double helix structure of DNA by Watson and Crick led to a huge wave of DNA studies. Seventeen years after their discovery, recombinant DNA (rDNA), also known as genetic engineering or gene splicing, was introduced to the world. It is a technology that has enabled a new and more precise type of genetic manipulation, not only across species lines but also outside the animal kingdom (Morgan, “The Genetics Revolution: History, Fears, And Future Of A Life -Altering Science.”) . With the identified functions of genes, scientists will in the future be able to add or remove traits exactly as they wish. Achieving this technology is only a matter of time. However, the difficulties arise more from the ethical questions raised than from the scientific research. Concerns about how modified humans will affect society become a hot topic, even sparking fear among some people. The birth of a new technology always accompanies ethical questions. Fear of genetic improvement spreads widely. One reason is that the technology of selecting genetic characteristics is immature, which could lead to unwanted changes in humans. Furthermore, genetic enhancement may result in unequal distribution. With the rich having their own “superchildren,” the poor would be less likely to narrow the gap between themselves and the rich.
