23andMe told me that I was a quarter Italian. Seemed to have mixed that up with what I actually am: 50% middle eastern. For a while I wondered if there was some funny business in the family, but then my sister got the "right" percentages. This seems like a pretty huge error to me.

I know it might can be assumed from the context of the post and thread but are you talking about your twin sister or not? Just pointing out that the chance for funny business (in your family or at your birth or at these companies) is unknown but not necessarily zero.

Well, Italian and ME populations were basically the same thing for more than a thousand years (basically until the Islamic Conquest promoted piracy on the Mediterranean, making it fundamentally unsafe). So it might well be that you are carrying genes that most of the Italian population also carries, and viceversa.

Is it possible one of you has a father that's 100% middle Eastern, and the other has a father 50% italian and 50% middle Eastern?
