The only known case of a Hyūga clan member having children with a non-Hyūga is Hinata and Naruto's, and both of their children didn't inherit the Byakugan. If I'm not mistaken, in Retsu no Sho it was stated that the Byakugan is recessive and as such the Hyūga Clan was extremely careful in preserving the kekkei genkai. Agreed, the byakugan being dominant makes no sense. Not only would everyone have the Byakugan, but the whole Main/Side branch system would make no sense whatsoever.
