@Rage gtx what im implying is that the reason Asura and effectively why Naruto does not have Rinnegan as was this topic been about and that the genetic make up of a child, or rather 2 siblings, with parents whom father is by far half-human and mother most logically full human, the chances of sharingan/rinnegan to asura/naruto is not in good favors for the 1/4 chance to gain sharingan at birth, unlock Indra who got it first.
