I may be missing something, but... 

Something I've been wondering for a bit, many sources say he was supposedly 2/3 god and 1/3 human, but how is this possible?  I cannot think of any combination of parents, grandparents, or however far back you want to go, that would result in being 2/3 anything.  Am I just missing something, or did the writers just not understand genetics/math very well?

Though I guess "godhood" doesn't necessarily have to be inherited from the parents.  It could simply mean that he was comparable to 2/3 of a god, or something?
