China’s state genetics claims political borders rest on genetic markers.

Evidence

Serological studies have also been carried out to highlight the biological proximity of all minorities to the Han. Mainly initiated by Professor Zhao Tongmao, estimations of genetic distance based on gene frequency are claimed to have established that the racial differences between population groups living within China - including Tibetans, Mongols, and Uyghurs - are comparatively small. … His conclusion underlines that the Han are the main branch of the “yellow race” in China to which all the minority groups can be traced: the political boundaries of the PRC, in other words, appear to be founded on clear biological markers of genetic distance (Zhao, 1987:351-71). — David Theo Goldberg, John Solomos, A Companion to Racial and Ethnic Studies, 3348

Categorization

• XREF: Connects to the social-construction-of-race literature and to how nationalist mythmaking converts genealogy into biology; resonates with the reader’s interest in how institutions legitimate authority.
• QUESTION: How does this Han-centric genetic science compare to the actual genetic diversity data modern population genetics has since established for China? Worth chasing later.
