On the sensations of direct-to-consumer DNA testing: realisations, resemblance and relationships

The field of genealogy has rapidly evolved with the rise of direct-to-consumer DNA testing, a digital technology with the potential to disrupt previously held understandings of family history. Recent theorisation in the sociology of personal life provides a useful lens to attune to potent sensations and affinities sparked by direct-to-consumer DNA testing. Our analysis focuses on the accounts of three donor-conceived people – Thomas, Simone and Amira – whose DNA discoveries significantly disrupted their familial, cultural and national identities. We explore three cascading flashes of insight derived from our analysis: realising and reordering the family tree – how DNA discoveries were experienced through a range of initial sensations from shock to stupidity to feeling cheated and duped; reflecting on resemblance – how DNA discoveries were felt through sensations of similarity and alterity; and re-evaluating relationships – how the sensations of DNA discoveries (re)shaped interactions with family. This article contributes to understanding donor-conceived people’s relational practices following DNA discoveries and the role of sensations in these practices. We argue that such sensations impact understandings of self and familial relationships, raising questions about social and genetic inheritance and who counts as family.
