The rinnegan originated with Kaguya. It was the eye of the ten tails. The gene was passed to Hagaromo who was able to unlock it as a natural progression of the mangekyou sharingan.
In order for Madara to unlock rinnegan he needed senju and uchiha dna.
Sasuke also had Hashirama cells when he unlocked his rinnegan. This is interesting because he has a child now. It makes me wonder if Sarada inherited senju and uchiha traits because of her father's rinnegan. Senju+Uchiha=Rinnegan. Rinnegan=Otsutsuki.
As her eyes progress she will display more senju or body type abilities also. Once she unlocks the rinnegan she will gain otsutsuki abilities also. Six paths chakra is definitely not out of the question. Its possible that she awakens six paths yin and yang.
