One of the things we love about Naruto is how deep it goes when it comes to theories and conspiracies. The Sharingan and Byakugan are one of the three great in Narutoverse. While the Sharingan lets the wielder traumatize the opponent, the Byakugan is more physical, in the sense that you have the ability to distort the flow of chakra. A combination of the two would be lethal. As Boruto gains momentum, we hope to see the combo in action. But the question right now is, what would happen if Boruto and Sarada were to get married in the future and have a kid? Will the kid posses both the Sharingan and Byakyugan or will there be a fusion of Kekkei Genkai’s?
The answer to this question is ‘Yes’. In an interview Masashi Kishimoto ( the creator of Naruto) revealed that a child with Hyuga and Uchiha as parents will have both the clan’s eyes. According to him, the right eye will have the Sharingan while the left will be possessed by the Byakugan of the Hyuga clan.
While Masashi Kishimoto makes sense, we can further validate the answer from the fact that Sarada Uchiha posses both the Sharingan and the monstrous strength of Sakura.
One case I want to look at particularly here is the case of Inojin, while many argue that he’s a combo, I completely disagree. The reason is, even though the artistic instincts were passed on to him by his father, it’s not a Kekkei Genkai. Also, Ino’s clan techniques are classified as Hidden Techniques which use Yin-Yang release which are taught and not passed via genetics.
