In this episode we address another issue that students come into class with when we try to teach about the cultural construction of race: the biological reinforcement of race that comes from commercials run by DNA ancestry companies that promise to tell you whether you should be wearing lederhosen or kilts.
​Methods of ancestry estimation:
