can someone explain to me why himawari and boruto has whiskers?

It probably means jin traits are genetic. I'm pretty sure the theory was those exposed to biju chakra before birth would get jin marks (Naruto and Gaara). After that, they must actually be genetic traits.

So biju chakra mutates your genes.

Do you think Mito and Hashirama's kids would have had whispers? Hehe, Tsunade even could have had them...
