I just wanted to point out a fallacy of one of your arguments. We don't know if the sharingan is a recessive trait. Just because it shows up in a minority of the Uchiha family doesn't make it reccessive. As an example: in my extended family, only a few people have brown eyes. The majority has blue eyes. Does that make brown eyes a recessive trait? No. It just means that, in this case, the recessive trait has proliferated itself enough to be found in the majority. This actually happens in a lot of families.

Similarly, in the Uchiha clan, only a few people have the sharingan. Does that make the sharingan a recessive trait? Not necessarily, although it is more likely. So you can't assume the sharingan is recessive or dominant.
um if you read my posts i already said that we dont know if the sharingan is recessive. I said pretty much what you said. And also, i didnt really know about the the super complications of genetics yet. Also, i dont know when it says that is only appears in few either.
