It’s conventional wisdom that procreation between first cousins is unhealthy. But what are the actual genetic risks?
James MacDonald describes some of the risks in a new article. He writes:
“In much of the world, consanguineous marriage between cousins is very common. For most Americans, however, marriage between cousins is at best a punchline, at worst a taboo. In many states, it is illegal for first cousins to get married. The objections are ostensibly based on the risk of genetic problems. But is there an actual risk?”
