Evidently, genetics is only one piece in the puzzle of personal and collective identity, and we should not confuse the two or ‘essensialise’ genetic identities. That would no doubt constitute a simplistic understanding of people’s personal or collective identities. As preliminary evidence suggests, individuals tend to employ genetically deterministic ideas to a much lesser extent than could be expected when it comes to their own bodies and lives (Prainsack and HashiloniDolev, 2008; Prainsack and Spector, 2006; Egorova and Parfitt, 2006; Gibbons and Novas, 2007). However, DNA is – and can effectively be turned into – a constitutive element of individual, group and collective identities. Indeed, this was the initial impetus for stressing the importance of ‘biosociality’ (Rabinow, 1992, 1999).
