If chakra works similar to genetics and genetics in Naruto work anything like in real life, then Boruto has at most: That means that Boruto at most inherited from Naruto a quarter of Asura's chakra, half of Naruto's own chakra (with Naruto's own chakra having a little fragment of Kurama's own merged into it as well, hence whiskers)
 * half of Naruto's chakras.
 * half of Hinata's chakra

I don't think that things like Hashirama's chakra or Hamura's chakra are inheritable, sorry folks. The reason is that they are not part of their genetics. Naruto has Hashirama's cells, not genes. Hinata might have Hamura's chakra, but not his genes. So why did I include Asura's chakra and Kurama's chakra you might ask. Well, Asura's chakra is a part of Naruto himself since the moment of conception I suppose? Same for Kurama's. So I believe those affected his DNA to an extent, while later power-ups did not, hence aren't part of his genetics, thus aren't inheritable, same for Hinata with Hamura's chakra.

Still, Boruto has quite good ancestry regardless. But as said by Hagoromo himself, children are not guaranteed to inherit their parents' power. Because genetics are mostly random + mutations etc. Just like Boruto and Himawari not having alien eyes and in Boruto's case the Byakugan doujutsu in itself whatsoever. But he has his own doujutsu. So considering I don't think any of Hamura's very own chakra touched Boruto, his doujutsu is likely not to be the Tenseigan either, but a completely new thing, unique to him... a mutation of the Byakugan. My theory is that some Rinnegan genes present in fragment of Asura's chakra that Boruto inherited mixed with some Byakugan genes present in half of Hinata's chakra, thus Boruto's doujutsu is half Rinnegan-half Byakugan. Which is interesting, because Byakugan is the aliens' own power, while the Rinnegan has origins in the chakra fruit, being a half of Rinne Sharingan, while Boruto might be the first merging the two.

If my theory will turn out true, fanon nerds will be happy and this will open up the possibility of even more doujutsu mergers in the canon, like Sharingan-Byakugan, Tenseigan-Rinnegan, Tenseigan-Sharingan.
