Boruto's Jogan VS Himawari's Byakugan

Both children are direct decendants of Ōtsutsuki, potentially are able to posses their ancestors chakra. They share the same DNA as well. The byakugan is hard for a non direct bloodline of the Hyuuga to possess. So, lets look at the genetics of these two young shinobi to be. The dominant Kekkei Genkai trait is the Byakugan, for even a deluded branch member of the Hyuuga clan are able to activate this doujutsu. It really depends on the nature of the chakra in which if the user will have one or both eyes being able to possess the Byakugan. Himawari chakra nature allows her to have both while Boruto only gains a single eye. The next dominant trait is the Ōtsutsuki bloodline. It has been officially stated that if a Byakugan user has a child with someone with chakra of Hamura Ōtsutsuki, over a certain period of time it evolves into the Tenseigan. In which, the Uzumaki clan are direct descendants of the twin, Hagoromo Ōtsutsuki aka Sage of the Six Paths and his son Asura Ōtsutsuki. So, the Tenseigan is out of the question of Boruto's mutated Byakugan. The question is, why did one only one of Hagoromo's sons get the Sharingan and the other did not? That would because of Kekkei Genkai (Bloodline Limit.) The genetics split because of mutation. Asura obtained the vase chakra nature while Indra got his doujutsu genetics. Back to Bourto and this Jogan. It is a result of Kekkei Touto (Bloodline Selection). Because of his interaction with Toneri, a descendant of Hamura. During this time with Boruto, Hamura could have added his chakra into Boruto when told him of an impending doom. It is known that chakra can be transferred. Boruto's Jogan Byakugan is a result of chakra mutation that Boruto has thanks to Naruto and Kurama, making his chakra more acceptable to absorb and change. The Jogan is a mutated Byakugan. The dimensional part is the easiest. It's the same as the Mangekyou Sharigan, it is a dominant trait of being a descendant of Hagoromo's doujutsu. If a child who possess a doujutsu and a decedent of Hagoromo, their doujutsu will have space-time abilities. Hamura has this as a recessive gene while Hagoromo has the dominant gene from their mother. This mutation is why Boruto's Byakugan is a Jogan, a pure eye. The Tenseigan is a result of a Ōtsutsuki-Hyuuga direct while the Jogan is a mutation of Uzumaki-Kurama Enhanced-Ōtsutsuki Chakra-Hyuuga direct. The Uzumaki's vast chakra reserves, Kurama's sage chakra, Naurto's Sage Chakra, Tonrei gifting his chakra, and the Hyuuga's famous Byakugan. Himawari could also gain the Jogan if a Ōtsutsuki transfers their chakra to her. Though, she could also develop the Tenseigan.
