'Sociology, Genetics, and the Coming of Age of Sociogenomics' by Melinda C Mills and Felix C Tropf in (2020) 46
Annual Review of Sociology comments
Recent years have seen the birth of sociogenomics via the infusion of molecular genetic data. We chronicle the history of genetics, focusing particularly on post-2005 genome-wide association studies, the post-2015 big data era, and the emergence of polygenic scores. We argue that understanding polygenic scores, including their genetic correlations with each other, causation, and underlying biological architecture, is vital. We show how genetics can be introduced to understand a myriad of topics such as fertility, educational attainment, intergenerational social mobility, well-being, addiction, risky behavior, and longevity. Although models of gene-environment interaction and correlation mirror agency and structure models in sociology, genetics is yet to be fully discovered by this discipline. We conclude with a critical reflection on the lack of diversity, nonrepresentative samples, precision policy applications, ethics, and genetic determinism. We argue that sociogenomics can speak to long-standing sociological questions and that sociologists can offer innovative theoretical, measurement, and methodological innovations to genetic research.
'The route to your roots: New ethnic symbols in the age of the genome' by
Hannah Carlson in (2020)
Nations and Nationhood comments
This study assesses the recent surge in popularity for genetic “ancestry” testing in the United States and what significance this has for Americans' use of symbolic ethnicities. Specifically, this study evaluates how commercial genetic tests allow for new engagement with a symbolic ethnicity and ethnic symbols (Gans, 1979). This study draws upon interviews, attendance of a genealogical conference and a virtual ethnography to support its arguments. The possibility of reification of ethnic, national and racial categories is discussed, alongside a discussion of the way genetic populations are technologically produced. This study draws upon the concepts of affiliative ethnicity (Jimenez, 2010); affiliative self‐fashioning (Nelson, 2008); geneticized identities (Roth & Ivemark, 2018) and Waters' Ethnic Options to argue that DTC genetic ancestry tests allow for a new type of play with ethnic symbols, resulting in cognizant engagement with symbolic ethnicities among Americans who take a genetic test with identity aspirations
