I agree, anything is possible in a fantasy show, and even if it was entirely possible that suddenly a UFO comes flying around and abducting the protagonists, I doubt that this will happen (I hope!....). Even a fantasy show has to follow a certain logic.

Maybe you are right and it is not about the gender but when we take a look at the kingdoms, they are all ruled by men. Annis has only become the ruler as queen because Caerleon died. There is not just one female ruler we know of (in case I haven't overlooked something. Please correct me if I'm wrong). So it is very likely that even here on Merlin it's the male offsprings that have the first right to the throne. It was also said that Uther wanted an heir, not an heiress. I do agree though that the female status quo here on Merlin is far more modern and emancipated than it actually was back then in reality.

But either way, Arthur is the legitimate child of the King and the Queen of Camelot and this alone qualifies him over Morgana who is the illegitimate child of the king only.
