Do you believe in love at first sight, or should I walk by again?
We now have the potential to banish the genes that kill us, that make us susceptible to cancer, heart disease, depression, addictions and obesity, and to select those that may make us healthier, stronger, more intelligent. (…)
During that year, fertility clinics across the country have begun to take advantage of the technology’s latest tools. They are sending cells from embryos conceived here through in vitro fertilization (IVF) to private U.S. labs equipped to test them rapidly for an ever-growing list of genetic disorders that couples hope to avoid.
Recent breakthroughs have made it possible to scan every chromosome in a single embryonic cell, to test for genes involved in hundreds of “conditions,” some of which are clearly life-threatening while others are less dramatic and less certain – unlikely to strike until adulthood if they strike at all.
And science is far from finished. On the horizon are DNA microchips able to analyze more than a thousand traits at once, those linked not just to a child’s health but to enhancements – genes that influence height, intelligence, hair, skin and eye color and athletic ability.
