That crossed my mind too. But then I figured they could get married without having sex;o
Actually, in the UK, the law is not just about preventing 'undesirable genetic mixing' but 'inappropriate relationships' - i.e. the law was recently updated to make foster and adoptive parents having relationships with their children unlawful (aside from age of consent issues). Clearly in these cases the resulting offspring would be genetically sound, even if slightly confused at Christmas 🙂
