It depends if the sharingan is a reccesive gene.
I have not done gene analysis on the sharingan phenotype. I couldn't tell you.
Traits like eye color are usually complex in the way they are genetically encoded and expressed. It comes down to more than a simple recessive/dominant allele.
Whatever i dont want to think it out >.<
The Sharingan gene doesn't appear in every child. It doesn't come in females either.
