The Phenotype/Genotype Distinction and the Disappearance of the Body

Abstract

The discipline of genetics has long been a rhetorical and heuristic locus for social and political issues. As such, the science has influenced culture through the avenues of law, medicine, warfare, social work, and even, since 1972 in California, the education of kindergarten students. It has affected how we view the body, morality, romance, biography, and agency-not to mention procreation and death. In many ways the delamination of genotype from phenotype was the first cut, so to speak, in this new cosmetics of life. The distinction between structure and expression arose from an interdisciplinary struggle for authority in the biological sciences at the turn of the century. This preceptual split in the organism between structure and expression came over time to fundamentally alter the percepts of the body, in terms of how the body is juridically, medicinally, and otherwise, generally perceived and understood. More importantly and interestingly, this delamination within the organism between its genotype and phenotype eventually led to a sense of the body's fragility and its eventual disappearance as a seat of agency, morality, and identity; and in turn these three groundings of modernity have been redistributed to the gene, the genotype, and the genome. In one sense, then, this paper traces not so much the birth of a new view of the body (the genetic) but the drama of its disappearance, in which the body melts to a silhouette and is replaced by the genotype and its expression, the phenotype.
