The moral significance of the genetic relation

Our ordinary moral attitudes give a prominent place to the principle that each person ought specially to care for any child who is his or her genetic offspring. From this principle of genetic-parental responsibility and other plausible premises, we can derive the principle that each person has the right to control the genetic use of his or her own genes. But there are competing principles of parental responsibility that require consideration. Principles of nurture are among the important competitors. Also, the view that a woman has the right to control her own body for reproductive purposes may be based on a principle that denies the genetic-parental principle. An analysis is developed of the relations that constitute the criteria for the various possible principles of parental responsibility. Causality, temporality, spatiality, and resemblance are considered. The genetic relation is not any one of these relations, but it includes some of them. The justification of any principle of parental responsibility requires a detailed consideration of the principle from the viewpoint of a deontological or consequentialist moral theory. This examination is beyond the scope of this paper, but consideration is given to some issues and problems of justification, and difficult or unusual cases are discussed. There remain, then, complexities that require further study.
