Unfortunately, this scheme also introduces an important equivocation into public health discourse between two different ways in which genetic screening might be thought to be preventive: genetic screening as a technique for preventing the expression of a genetic disease in an individual and genetic screening as a technique for preventing the inter-generational transmission of disease genes.
