All lore sources seem to indicate the Camoran Dynasty are a powerful family from Valenwood. Furthermore The Refugees explicitly describe the mother of Mankar and the concubine of Haymon to be a Bosmer.
Even if his father were mostly Ayleid as many powerful Valenwood rulers are, shouldn't he take on more of the physical characteristics of the mother?
I know a lot has been said about his ability to wear the Amulet of Kings over the years but that's not the most bizarre part about his genealogy to me. Judging from everything we're told about mixed race children and about the Camoran family, the main villain of TES IV should have been a short little Wood Elf.
Do you think Bethesda chose to ignore this lore because it would seem silly to make the character who is for all intents and purposes the final real boss of one of their games be from the same race as Fargoth or the Adoring Fan, or is there some deeper reason that escapes me?
