race and genetics

Race is a social construct used to categorize humans based on physical traits like skin color, but it doesn't have a strict biological basis. Genetic differences among individuals are tiny and don't align neatly with racial categories. Most genetic variation occurs within so-called racial groups rather than between them. This means race is not a reliable way to predict genetic traits or health, as all humans share about 99.9% of their DNA. In short, race is more about social identity than clear biological distinctions, and our shared genetics emphasize our common humanity.
