From a genetic point of view, all humans are remarkably similar. Indeed, when the Human Genome Project was completed in 2003 it was confirmed that the “three billion base pairs of genetic letters in humans [are] 99.9 per cent identical in every person.” There are, of course, genetic differences that occur more frequently in certain populations – lactose intolerance, for example, is more common in people from East Asia. And valuable research has explored the health significance of genetic variation. But there is simply no reason to think that your genes tell you something significant about your emotional connection to a particular cultural heritage. There isn’t a lederhosen gene.
