To my understanding, people with Kurama's genetics have whiskers.
Kinkaku (3 Whiskers): Ate Kurama's flesh.
Ginkaku (3 Whiskers): Ate Kurama's flesh.
Naruto (3 Whiskers): Born from Kurama's jinchuriki.
Boruto (2 Whiskers): Born from Kurama's jinchuriki.
Himawari (2 Whiskers): Born from Kurama's jinchuriki.
Now here's the question, if that's the case, then why does Boruto and Himawari have 1 less whisker? Does that mean their whiskers are inherited not from Naruto being Kurama's jinchuriki, but from Naruto himself?
Also, that means Mito's children should have 3 whiskers too, Tsunade and Nawaki then would have 2 whiskers, but that's not the case for some reason.
both Naruto, kinkaku, and ginkaku had first lvl contact with kurama.. and kushina was the mother and jinchuriki, so Naruto had contact with kurama all the time, while Naruto was the father, so the contact wasn't as constant.. but the mito thing doesn't make sense, ill agree on that.
Ginkaku and Kinkaku have whiskers because they are distant related to Hagoromo. That's why after eating Kurama's flesh they didn't die (other people that ate his flesh die) Mito descendants doesn't have whiskers because kurama's genes decrease every generation, that's why Hima and Boruto have 2 whiskers. Maybe their children will have 1 whisker.
