Can we "design" a baby like we design a handbag? It may sound crazy, but a "designer baby" could be possible now. Of course, at the same time, there are both agreements and disagreements with it.
The "designer baby" idea comes from the research that allows scientists to make changes to human DNA and genes (基因). Usually, it is done when the baby is still just an embryo (胚胎). By doing that, scientists hope that "designer babies" will less possibly be born with some certain serious illnesses.
During the 21st century, the idea became so popular that the research developed very quickly. Now, it has been firstly used to help born babies with their illnesses. One example of this is that Dr. Adrian Thrasher of University College London was able to save a 1-year-old child from leukemia (白血病) with the help of it. People learned that it was not only illnesses they could change, but also a baby'sgenderand looks. A well-known event happened in 1996. An American couple, Monique and Scott Collins, decided to use this research to help them choose the gender of their next baby. They wanted to have a baby girl for they have had three sons. Moreover, people could also decide babies' eye color, hair color and even things like height or how sportive babies will be.
Some people argue that it is not ethical (道德的)to design babies like designing a bag. It is strongly against the nature's rules. Besides, it may not have any bad influence on the baby now, yet no one knows what will happen to him and his children after many years.
