Degrees of Mixture, Degrees of Freedom: Genomics, Multiculturalism, and Race in Latin America
From Eugenics to Blood Types
Chapter 2 looks at genetic studies carried out from the 1940s to the 1970s. These focused mainly on indigenous peoples, but necessarily explored processes of mestizaje. The studies took place at the time of a global shift toward antiracism, which depended on a strict divide between biology and culture, which undermined the authority of the concept of race (without abolishing it altogether). The chapter explores eugenics, and moves on to specific genetic studies of blood types.
