Bending isn't hereditary. It's pure chance. And the bending type depends on your nationality. If you're family is from the Water Tribe, you're either gonna be an waterbender or non-bender, same with other nations. If you're family is from the Air Nomads and Water Tribe, you're either gonna be a non-bender, airbender, or waterbender.
