 The article "Introduction to Sociology/Race and Ethnicity" on Wikibooks explores the concept of race and ethnicity from a sociological perspective. It delves into the social construction of race, highlighting how race is not a biological fact but a social construct that varies across cultures and time periods. The text discusses different racial classifications in countries like Brazil and the United States, illustrating the fluid and subjective nature of racial categories. Additionally, it examines the intersection of race with biology and genetics, noting the controversies and debates surrounding genetic differences among races and their implications for health and disease research. The article also covers prejudice, bias, and racism, providing definitions and exploring their impacts on society.

1. Racial Classification in Brazil: The Brazilian Institute of Geography and Statistics classifies people into five racial categories based on self-identification, illustrating the social construction of race. The "pardo" category, which falls between "white" and "black," exemplifies the fluidity of racial boundaries in Brazil compared to the United States​ ​.
2. Genetic Clusters and Race: Genetic research shows that genetic variation within racial groups is often greater than between them, challenging the biological basis of race. However, some studies use genetic markers to create clusters that correlate with self-identified racial groups, sparking debate on the validity and implications of these findings​ ​.
3. Impact of Prejudice and Bias: Prejudice, bias, and discrimination are distinct yet interconnected concepts. The article discusses how prejudice can be taught and socialized, and how biases can develop from direct experiences. It also highlights that while some argue for an innate preference for one's own racial group, most prejudicial attitudes are learned and can be unlearned​ .
