Well Naruto didn't have any Uzumaki sealing jutsus, chakra chains like Kushina, a sensor like his dad (Naruto is 50% Namikaze) or Karin and Nagato so does that mean he's not a Uzumaki? He was only given the name Uzumaki because Hiruzen feared Minato's enemies would go after Naruto had they known he was Minato's son. In part 1 Sasuke said himself that the Sharingan awakened in a selected few Uchihas but that didn't make those without the Sharingan's non-Uchihas.If you are looking for a fact that his mother is a hyuga just to make you happy then that he is, but if you looking at logical sense, he has none.
Himawari isn't a Hinata clone, she isn't anywhere near as reserved as Hinata is/was...Only Himawari has one because she's not only has byakugan, but she also soloed naruto with Jyuuken which is a proof that her KKG is there. Kishi loves to make copies of Himawari= Hinata to be only hyuga while Bolt = Naruto
So stupid it hurts..Oh you mean more or less 5% genes when boruto tries to copy a jyuuken which has no effective at all??
But Naruto still had the Uzumaki vitality, stamina, and chakra reservesWell Naruto didn't have any Uzumaki sealing jutsus, chakra chains like Kushina, a sensor like his dad (Naruto is 50% Namikaze) or Karin and Nagato so does that mean he's not a Uzumaki?

Kishi didn't make Bolt like Naruto, he's suppose to be a prodigy unlike Naruto. Bolt is still young, his sister can be a fast bloomer is all since Kishi might use the whole female mature faster than guys angle here.
