the rinne-sharingan is sort of like the parent of both since they got the powers from ten tail tree fruits and all ten tails possess rinne-sharingan. kaguya's manifestation just seems to be the most genetically complete out all examples we have seen. currently there is no evidence of sharingan/mangekyo being present in the otsutsuki clan outside of the tomoe rinnegan though we atleast know from kaguya that amaterasu was likely seen in their clan.
