If the various "superpower" ninja traits are considered "blood traits," how is
it someone like Kakashi, who is in no way related to the Uchiha clan, can use
the Sharingan Eye technique?

More fully: would transplanting work on _any_ bloodline trait power? If
someone had a bloodline trait that worked on arms, could they just transplant
their arm onto another person and then there would be two people with that
technique?

How is it that a Sharingan can work when it's been transplanted?


I'm not sure about other bloodline jutsu, but the Sharingan's power lies
within the eye. So whoever controls a Sharingan eye gains its powers.

It may be possible to gain other bloodine jutsu, but to determine where the
actual jutsu is located within their body or even the chakra system is still
speculation. For now, we know that those jutsu that comes from eyes, Sharingan
and Rinnegan are up for grabs, not sure about others though.

Let's disregard the fact that eyes in Naruto are considered less difficult to
work with than PnP displays. (Rin did it in a cave, without any medical
supplies, in a couple of seconds, and it just _worked_ )

Your eyes contain your DNA, so our (the Uchiha) eyes contain the already
awakened Sharingan, it's written into the DNA.

It also has the genetic information allowing you to activate the techniques
the eye holds (including Mangekyo).

The Sharingan being transplanted will work, as you've noticed with Kakashi.
However it won't be as effective.

Sharingan original users, the Uchiha clan, can use the techniques with ease,
but Kakashi needs to rest more often. This is due to the fact that since he's
not an Uchiha member, these techniques will use up his chakra much faster.

Kakashi has it all covered, except in battles, because he cannot deactivate it
and it would, like I said above, consume his chakra in vain.

He's not the only one that does a transplant. Also,

> Danzo, Tobi transplants the Rinnegan and steals it and Sasuke receives new
> eyes.

I suspect the same would happen for other transplants but I have no examples
off the top of my head.

A non-Uchiha cannot advance their Sharingan. As seen with Danzo and Kakashi.
The only reason Kakashi had a Mangekyo Sharingan is because Obito saw Rin die.

This is explained by Tobirama when he tells about the Uchiha's brain, how
their pain and hate change their brain physiology and functioning, allowing
them to turn that pain into the Sharingan. As their pain and hate grow, so
does their power.

If a brain isn't an Uchiha brain, and thus does not have this special area of
the brain, then they will not:

A.) Naturally gain a Sharingan

B.) Awaken the different stages of the Sharingan.
