A Eugenic Effect of Medical Care


When sophisticated medical attention substantially increases the life expectancy of individuals with a severe homozygous condition without significantly raising their reproductive success, an increase in parental investment should render a concomitant decrease in parental ability to reproductively compensate. This process will lower the expected number of heterozygous carriers produced by heterozygous parents and, in turn, will lower the equilibrium frequency of the gene.
