@Ultimadude their eyes are indeed a different shade of blue with himawari’s being noticeably lighter also none of the individuals who got whiskers were jinks (naruto had whiskers prior to becoming a jink). So there is obviously a difference between having the biju sealed in you compared with having it’s chakra directly infused in your bloodstream. Naruto in the womb, boruto and himawari bring sperms created from naruto’s cell/blood and the twins ingesting Kurama’s chakra directly sending it into their bloodstream.

And I’m almost certain that I’m right as time will reveal the twins also confirms this, since it’s virtually scientifically and mathematically impossible that all of them would have exactly the same mutation. And think you are the one reaching with the origin of their whiskers they obviously got it from being in and ingesting kuruma’s chakra that is the latent cumulative effect of his chakra in the bloodstream.
