Anyway, there are a few scientists -- mostly Asian -- who continue to do research on human genetics that includes mention of race. And they of course uniformly find that the allegedly "social" construct of race in fact has an overwhelmingly genetic basis. The more genetic markers they use, the more accurately they can tell what your racial origins are. I reproduce the abstract of the latest such study -- by Tang et al -- below. Note that they could even pick out Hispanics reliably on the basis of their genes -- presumably because Amerindians are distinct genetically and "Hispanics" are in fact mostly Amerindian.
"We have analyzed genetic data for 326 microsatellite markers that were typed uniformly in a large multiethnic population-based sample of individuals as part of a study of the genetics of hypertension (Family Blood Pressure Program). Subjects identified themselves as belonging to one of four major racial/ethnic groups (white, African American, East Asian, and Hispanic) and were recruited from 15 different geographic locales within the United States and Taiwan. Genetic cluster analysis of the microsatellite markers produced four major clusters, which showed near-perfect correspondence with the four self-reported race/ethnicity categories. Of 3,636 subjects of varying race/ ethnicity, only 5 (0.14%) showed genetic cluster membership different from their self-identified race/ethnicity. On the other hand, we detected only modest genetic differentiation between different current geographic locales within each race/ethnicity group. Thus, ancient geographic ancestry, which is highly correlated with self-identified race/ ethnicity-as opposed to current residence-is the major determinant of genetic structure in the U.S. population. Implications of this genetic structure for case-control association studies are discussed".
Still, I suppose all those Leftist "intellectuals" who cannot believe the evidence of their own eyes as they walk down the street (all those black skins are "socially constructed", don't you know?) are not going to be much moved by research of any kind. The PDF of the whole study is here
