How do you know that Byakugan is dominant? 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.
