It’s frequently noted that the Lancaster Amish population descends from a relative handful of immigrant families (see this explanation of genetic drift and the founder principle).To the non-scientific public, “inbreeding” is a stomach-churning word which in its worst sense suggests sexual relations between close (nuclear) family members.Though criminal cases of abuse have occurred these types of relationships are not sanctioned by Amish.It’s really the language used to describe it which may not be quite so helpful.In the article describing the work, researcher José Luis Rosa of the University of Barcelona states that “in these communities there are high rates of inbreeding, so homozygous recessive diseases are more frequent than in general population”.“High rates of inbreeding” struck me, and I’m now predictably seeing the term pop up in other places to describe the Amish.
