<Snipped quote by Masaki Haruna>
I don’t know what Buddha’s ruling on this, but when I ran a similar RP I went by the theory that only one (dojutsu) kekkei genkai would come out genetically— basically you only have one even if genetically you descend from two clans who both hold such kekkei genkai. It makes no sense to me to have both— one would or should overwrite the other. Recessive vs Dominant genes and all that.

Like Buddha said, Kaido doesn't have either. But, I agree with what you're saying. You'd have one or the other. Perhaps a mutation on one taking on the traits of the other. Sharingan with 360 degrees vision, or Byakugan that can predict moves. Not that it's relevant. I made Kaido Uchiha - Hyuuga in order to build up expectations for him to have a crazy KG, only to give him none.
