Suggesting that Kaguya had the same eye as the Shinju, the god of narutoverse just "because" before eating its fruit is illogical and contradicts what we know that she came there to eat its fruit and was first to use chakra from doing so. She might have had 3 eyes before for all we know, considering the horns, but the third eye definitely became whatever *Gan it is only afterwards. And you agree that chakra exposure may equal a genetic mutation, therefore how are the Tailed Beasts' advanced natures not a kekkei genkai, since they are because of their special chakra? They have flesh and blood, therefore likely genes too.
