Researchers are trying to dismantle the flawed concept of homogeneous racial mixing that has fostered discrimination in Mexico, Brazil and other countries.

Nicéa Quintino Amauro always knew who she was.

She was born in Campinas, the last city in Brazil to prohibit slavery in 1888. She grew up in a Black neighbourhood, with a Black family. And a lot of her childhood was spent in endless meetings organized by the Unified Black Movement, the most notable Black civil-rights organization in Brazil, which her parents helped to found to fight against centuries-old racism in the country. She knew she was Black.

But in the late 1980s, when Amauro was around 13 years old, she was told at school that Brazilians were not Black. They were not white, either. Nor any other race. They were considered to be mestiços, or pardos, terms rooted in colonial caste distinctions that signify a tapestry of European, African and Indigenous backgrounds. And as one single mixed people, they were all equal to each other.

The idea felt odd. Wrong, even. “To me, it seemed quite strange,” says Amauro, now a chemist at the Federal University of Ubêrlandia in Minas Gerais and a member of the Brazilian Association of Black Researchers. “How can everyone be equal if racism exists? It doesn’t make sense.”

Amauro’s concerns echo across Latin America, where generations of people have been taught that they are the result of a long history of mixture between different ancestors who all came, or were forced, to live in the region…

The analysis of these examples from Brazil, Colombia, and Mexico reveals how crucial the nation is as a frame for understanding the way racialized concepts get reiterated and reworked in genomic science, in ways that make race both disappear and reappear. Public health, multiculturalism, and forensics are all political and policy domains that directly invoke the biopolitical nation and its people in terms of their well-being, their diversity and unity, and their biological relatedness in procreation, violence, and death. The governance of these domains is of central interest to the state. Genomics also intervenes in these domains, with the promise of better health for the nation’s people, representations of both diversity and unity, and techniques for connecting bodies in ways that, it is hoped, will lead to reconciliations and peace. The idea of race, in previous times, figured explicitly in the way all these domains were conceptualized in all three countries—los problemas de la raza, to recall the title of the 1920 Colombian book cited earlier on, concerned precisely health, progress, unity, diversity, and conflict in the nation. Race was of course not the only factor to be considered—violent conflict, for example, also followed cleavages of class, region, religion, or political faction—but it was an important way of thinking about difference and the problems it might cause within the nation. The demise of race as an explicit discourse for talking about these matters did not mean that racialized concepts disappeared. Geneticists and medics continued to be interested in the racial mixture of their national populations in relation to public health, cultural commentators continued to reflect on diversity in terms of black, indigenous, and mestizo cultural traits, and indeed forensic scientists continued to classify bodies in more or less explicitly racial terms. Genomics, characterized by its very detailed examination of the structure of DNA sequences, generally rejects a language of race, both biologically and, in Latin America, socially. Brazil, where color/race labels operate in some domains, is a partial exception, while also being the country where the most vocal rejection of race is to be found. Yet, as we have seen, racialized concepts continue to appear implicitly (and occasionally more explicitly) in genomic analysis and are frequently harnessed to the idea of the nation.

Recent work on genomics and race makes the argument that concepts and categories of race are subtly reproduced in the practice of genomic science, despite the explicit rejection of race as meaningful biological reality by many geneticists. Our argument in this paper is that racialized meanings in genomics, rather than standing alone, are very often wrapped up in ideas about nation. This seems to us a rather neglected aspect in the literature about genomics and race. More specifically, we characterize race as an absent presence in Latin America and argue that genomics in the region finds a particular expression of race through concepts of nation, because this vehicle suits the deep-rooted ambiguity of race in the region. To make this argument we use data from an ethnographic project with genetics labs in Brazil, Colombia, and Mexico.

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.
