@Namikazenaruto9 Anime-only filler hardly proves anything.

@Narutonamekaze Not quite. While Byakugan and Sharingan originated from same source(Kaguya's Byakugan and Rinne Sharingan), they got seperated with her sons(Hagoromo getting Rinnegan while his son Indra and his descendants, Uchiha clan, getting Sharingan and Hamura and his descendants, Moon Ōtsutsuki and Hyūga clan, getting Byakugan). Hamura would then later awake his own "Rinnegan", Tenseigan.
