Gene-Environment Interplay

The notion that only social facts can explain social phenomena, which was argued by Durkheim, has confined Sociologists to seek explanations other than social factors for a long time. As a diverse of disciplines develop understandings of social behaviors and phenomena, Sociologists have chances to converse with other subjects, abandoning the unnecessary boundary which restrict them for decades. This would be an opportunity for sociologists to both refine the old and construct the new social theories that can describe and explain the society more adequately. One powerful challenge toward sociologists comes from Biology. Not only the evolutionary view from it provides insights to the topics of mate selection, group identification, prosocial behaviors, …show more content…

The contributions of the idea and findings of gene-environment interaction to Sociology, stated by Guo et al. (2015), include the discovering of the hidden contextual effects, understanding the complicated interplay, identifying the people who are the most sensitive to a certain exposure, and designing the intervention. As for the roles of genes within gene-environment interplay in Sociology, three roles have been proposed by Pescosolido et al. (2008): 1. Genes function as a social mediator which shape the social processes. 2. Negative social factors might suppress or trigger the expression of genes. 3. Some harmful life events or stresses could be amplified or modified by genes. The idea of gene-environment interplay is more prominent when we view issues from the life course perspective. The trajectories of life, among all the dimensions (education, work, family, health, etc.), are not only shaped by the interactions between social factors (ExE interactions, sometimes across layers (individual and structure)), but also by the gene-environment correlations (rGE) and interactions (GxE) (for full interplay descriptions, see GxE interaction sections). All of the life course components, such as the timing of the events, duration, and dimensions, can interact with genes to shape the individual outcomes (Shanahan and Boardman 2009). The integration …show more content…

Both social and biological pathways might contribute to the intergenerational transmission of educational attainment. As data and genetic information became available, sociologists tried to distinguish the two pathways and investigate the interactions between them. I will summarize several of them below. First, status attainment has always been a central concern for sociologists. Education, a critical achieved status which relates to countless outcomes, is shaped by both social and biological factors. For example, Guo and Stearn (2002) studied whether family background shapes the influence of genetic endowments on intelligence. By using the twins and siblings data from Add Health and the multilevel models, they found that the realization of their genetic potential depends on whether the parents were employed or not, and their ethnicity. The findings suggest that the effects of genes are conditional on social circumstances. Incorporating the relative new waves of Add Health data, Nielsen and Roos (2015) used the ACE models to investigate the educational attainment of the young people in the US. They partial out the variances into three components: genetic, shared environment, and non-shared environment. The findings are that the genetic component only explained 23% of the variance, and the shared family environment component accounted for 41% in twin and 30% in non-twin sibling samples. The
