  Two reasons are given for the use of reprogenetic technologies in this way. First, according to some liberal eugenics proponents, non-disease traits such as intelligence, memory, sex, hair or skin color, height, or beauty affect people’s wellbeing (Savulescu 2001; Harris 2005; Green 2007). Sometimes their effect on wellbeing is at least as significant as that of some diseases.  If so then, using reprogenetic technologies to select or edit some of those traits would be morally permissible.
