If Hohenheim is a homunculus (I know that he still has a humanoid body, because otherwise he wouldn't even have had children) and he has a family with Trisha, who is human, does this mean that the Elric brothers are half-human and half-homunculus?
Also, just to make sure, the Elric brothers are half-Amestrian and half-Xerxian (i.e. with a background from Xerxes), right? They don't explain that in either series.
