> So when you refer to those countries and religions ‘inbreeding’ you’re only talking about when cousins mate. Right?
That’s the most common form, particularly in Muslim countries that had been Arabised culturally through conquest or trade. Among them marrying your father’s nieces is the most common form by far as it helps preserving the clan’s resources in patrilineal line. I understand that this practice is genetically particularly detrimental. The preferred scientific choice of words is consanguineous marriage which is a mouthful, „inbreeding“ gets understood by everyone–I don’t mince my words anymore.
