a child born with sharingan must have xx and can't be xX or Xx since capital X is dominant.
if sasuke (xx) and random non-uchiha (XX) were to have a child, the posibilities are: xX, Xx, xX, and Xx. therefore, sasuke can't have a child born with sharingan with a random non-uchiha female.
sasuke MUST be recessive since he said that only a few select members are born with sharingan. most people have at least one of the dominant (X) genes in their blood, and only a few have both recessive genes (xx). that's why only a small number of them have sharingan.
and even if sasuke were to have a baby with sharingan, the kid would have to be a full uchiha to be able to use mangekyou sharingan. which is why the sharingan is so deadly.
i don't know, i might be missing something.
