What is the relationship between the Byakugan, Rinnegan, and Sharingan?


Can anyone brief a little about the link between the Byakugan, Rinnegan, and
Sharingan? I know the meanings, but I don't know the relationship between the
eyes.




The progenitor of chakra, Kaguya Otsutsuki, was the first character
(historically) to have Byakugan on Earth.

After eating the Chakra Fruit, she awakens a third eye on her forehead, the
Rinne Sharingan.

Now the Rinne Sharingan is completely independent of the Byakugan's influence.
This is because the [Rinne
Sharingan](http://naruto.wikia.com/wiki/Rinne_Sharingan) is the result of the
manifestation of the powers of the Chakra Fruit on a person.

When her two sons, Hagoromo and Hamura were born, they had their mother's
Byakugan. As time progressed, Hagoromo awakens a new dojutsu, the Sharingan.
In the anime, Hagoromo awakened the Sharingan after finding the corpse of his
love interest Haori.

The Sharingan is a derived form of the Rinne Sharingan, meaning, weaker. But
powerful nevertheless. He goes on to attain the Mangekyou Sharingan also, but
that is not shown on screen.

Hagoromo then achieves the Rinnegan, after nearly killing his brother (and
thereby freeing him from his mother's control).

The Rinnegan is a much more advanced form of the Sharingan and it has a wide
range of powers. The Rinnegan is stated to be something that is unique to the
Sage of Six Paths, which is why, to obtain the Rinnegan, shinobi mix the
chakra of Ashura and Indra (thereby getting Hagoromo's chakra).

While the Byakugan doesn't have any direct link to the Rinnegan and Sharingan,
it does play a significant role in their creation, along with the Rinne
Sharingan.
