Abstract

In recent years, there has been an intense debate about the concept of “biological” or “genetic citizenship.” The growing literature on this topic mostly refers to the importance of patients’ associations, disease advocacy organizations, and self-help groups that are giving rise to new forms of subjectivation and collective action. The focus is on the extension of rights, the emergence of new possibilities of participation, and the choice-enhancing options of the new genetics. However, this perspective tends to neglect the potential for exclusion and restriction of citizenship rights based on biological traits. We aim to broaden and complement the existing theoretical discussion on biological citizenship, which so far has concentrated on the medical sphere, by investigating a new empirical field. The article analyzes the use of DNA analysis for family reunification and shows that biological criteria still play an important role in decision making on citizenship rights in nation-states. Presenting Germany as an exemplary case, we argue that the use of parental testing endorses a biological concept of the family that is mobilized to diminish citizenship rights. The argument is based on documentary analysis and on interviews with representatives of nongovernmental organizations and immigration authorities, lawyers, geneticists, and applicants for family reunification.
