Alduin is not related to Akatosh in any form. They are a totally different being. Akatosh is one of 9 divine pantheon, while Alduin is the other way around. And to any of you wondering "how could Alduin be killed by any mere mortal if he is the god of destruction?" No he's not dead. After you defeated alduin, Paarthurnax told the Dragonborn that Alduin will return to fulfill it's destiny as the world eater, and probably no one can stop him at that time stating that there will no other Dragonborn "The last Dragonborn"
