A child with 3 genetic parents? It's a daunting possibility
What would be the moral implications of producing a child with three biological parents? The National Catholic Register offers a disturbing but thought-provoking analysis of that question—which, unfortunately, is no longer far-fetched.
Scientists in Oregon have discovered a way to transplant the nucleus from an egg supplied by one woman into an egg supplied by another donor. When fertilized by a man’s sperm and implanted in a woman’s womb, the resulting embryo would carry genetic material from three different people. The process, which would be carried out through in vitro fertilization, offers a means of overcoming mitochondrial disease.
Rebecca Taylor explains in her Register analysis that the scientists’ approach in this case is morally unacceptable for several reasons: because it involves in vitro fertilization, which separates procreation from the marital act; because it is dangerous to the unborn child; and because it involves genetic engineering, which opens the door to a host of frightening abuses.
Unfortunately the Church’s teachings do not dictate American public-policy decisions, as the rising popularity of in vitro fertilization proves. Federal officials could approve the creation of 3-parent embryos, citing the very legitimate need to counteract mitochondrial diseases as a justification. Indeed Taylor reveals that at least two children have already been born with genetic material from three donors!
Quite apart from the moral implications, these artificial-reproduction techniques could create some knotty legal problems. Would the courts recognize the woman who donated the nucleus as the sole legal “mother” of the child? What about the woman who donated the egg, containing the mitochondrial DNA? What are the legal implications of recognizing three parents for one child?
