Ethnic-racial classification criteria are widely recognized to vary according to historical, cultural and political contexts. In Brazil, the strong influence of individual socio-economic factors on race/colour self-classification is well known. With the expansion of genomic technologies, the use of genomic ancestry has been suggested as a substitute for classification procedures such as self-declaring race, as if they represented the same concept. We investigated the association between genomic ancestry, the racial composition of census tracts and individual socioeconomic factors and self-declared race/colour in a cohort of 15,105 Brazilians. Results show that the probability of self-declaring as black or brown increases according to the proportion of African ancestry and varies widely among cities. In Porto Alegre, where most of the population is white, with every 10% increase in the proportion of African ancestry, the odds of self-declaring as black increased 14 times (95%CI 6.08–32.81). In Salvador, where most of the population is black or brown, that increase was of 3.98 times (95%CI 2.96–5.35). The racial composition of the area of residence was also associated with the probability of self-declaring as black or brown. Every 10% increase in the proportion of black and brown inhabitants in the residential census tract increased the odds of self-declaring as black by 1.33 times (95%CI 1.24–1.42). Ancestry alone does not explain self-declared race/colour. An emphasis on multiple situational contexts (both individual and collective) provides a more comprehensive framework for the study of the predictors of self-declared race/colour, a highly relevant construct in many different scenarios, such as public policy, sociology and medicine.

In genetics laboratories in Latin America, scientists have been mapping the genomes of local populations, seeking to locate the genetic basis of complex diseases and to trace population histories. As part of their work, geneticists often calculate the European, African, and Amerindian genetic ancestry of populations. Some researchers explicitly connect their findings to questions of national identity and racial and ethnic difference, bringing their research to bear on issues of politics and identity.

Based on ethnographic research in Brazil, Colombia, and Mexico, the contributors to Mestizo Genomics explore how the concepts of race, ethnicity, nation, and gender enter into and are affected by genomic research. In Latin America, national identities are often based on ideas about mestizaje (race mixture), rather than racial division. Since mestizaje is said to involve relations between European men and indigenous or African women, gender is a key factor in Latin American genomics and the analyses in this book. Also important are links between contemporary genomics and recent moves toward official multiculturalism in Brazil, Colombia, and Mexico. One of the first studies of its kind, Mestizo Genomics sheds new light on the interrelations between “race,” identity, and genomics in Latin America.

In the contemporary world, “race” narratives are so multifaceted that at times, different views of the concept appear mutually incompatible. In recent decades biologists, especially geneticists, have repeatedly stated that the notion of race does not apply to the human species. On the other hand, social scientists claim that race is highly significant in cultural, historical, and socioeconomic terms because it molds everyday social relations and because it is a powerful motivator for social and political movements based on race differences. In this paper we present the results of an interdisciplinary research project incorporating approaches from genetics and anthropology. Our objective is to explore the interface between information about biology/genetics and perceptions about color/race in Rio de Janeiro, Brazil. We argue that the data and interpretation of our research resonate far beyond the local level, stimulating discussion about methodological, theoretical, and political issues of wider national and international relevance. Topics addressed include the complex terminology of color/race classification in Brazil, perceptions about ancestry in the context of ideologies of Brazilian national identity, and the relationship between genetic information about the Brazilian population and a sociopolitical agenda that turns on questions of race and racism.

This unique edited collection brings together biologists, geneticists, and social and biological anthropologists to examine the connections between genetics, identity, and health in South America. It addresses a wide range of theoretical issues raised by the rapid changes in the field of genetic sciences. Contributors come from Brazil, Colombia, Argentina, Uruguay, the UK, and the United States, providing a comparative cultural perspective for scholars, researchers, and students.
