Why don't Uchihas pass their eyes down generations?

[SenseiSama]

1. Because only transmigrants can gain EMS

2. Because they already pass down Sharingan you won't see Senju passing down Sage Mode

3. Because that's how you spread AIDS and hepatitis

They do, and it's too obvious. How? Well the story of Izanami and Izanagi and that of EMS. Several Sharingans were used to learn the secrets of MS, and we all know that the eye seals itself. An Uchiha without Sharingan is blind. It would make sense for them to pass on the eyes of the fallen comrades and Obito also knew how to take care of a large Sharingan stash; something he obviously learned from Madara.

Izanami was also a technique Uchihas developed to counter Izanagi abuse. That would also require plenty of blind and useless Sharingans, created in the process of technique construction.

So yes, they did.

 

[Arima]

Why don't Uchihas just pass their eyes down to their children after death? It'd be so much more advantageous than having to restart the entire process of leveling up your eyes.

You need to die and be buried with your eyes to rest in peace.

1.) No

2.) Genetically, yes, but not by giving their children their actual eyes. The senju part doesn't matter with this.

3.) Tell that to Madara, Kakashi and Obito
