People like Kabuto and Obito thought so, but Hagoromo and Black Zetsu are more credible in this, and they say it's the transmigrants specifically. Ashura and Indra's Chakra (which can act like DNA, except not all chakra can) is enough. Though i'd like to stress that in order to inherit that power fully one needs flesh (IE the ability to produce more of that chakra). That's kinda what I meant. The Rinnegan can ONLY be produced by transmigrants, simply having access to Senju and Uchiha DNA isn't enough, possessing Asura and Indra's chakra is absolutely necessary.

It's why I suggested that transmigrants tend to be born within the Senju/Uzumaki and Uchiha clans.
