According to Noahide law, only those related from the mother's side are considered blood relatives with regard to forbidden realtions. In other words, a half-brother is technically permitted to marry his half-sister IF she is from the same father but from a different mother. But today Noahides refrain from this. A Noahide woman is prohibited to marry a son from another wife of her late or divorced husband, and a Gentile is prohibited from marrying a Jew.
