What is an Advanced-Bloodline Ability?
An Advanced Bloodline Ability is an Ability that you cannot Preform without you having the same Dna Bloodline as the preformer.

Sharingan
An eye that appears to a selected few of the Uchiha-Clan members. Sharingan is an eye controlled by ones chakra, it allows the Sharingan-user to see through Genjutsu , Kage-Bunshins and to copy any Ninjutsu that is not from an Advanced bloodline.

Byakugan
Also Known as "White eyes". The Byakugan is an devastating eye that apperas to the Hyuuga clan. It gives the user the ability to see around him 359degrees . With the byakugan you can also see the main Chakra-center and the tenketsu (chakra holes) inside a persons body. That provides a great advantage becouse there are 361 Chakra holes in the body with only a diameter as the top of a needel. If you hit excatly the right spot of the tenketsu you can ’’Control the victims chakra usage’’ that means if you manage to hit all the 64 chakra openings (a tenketsu spot where the chakra comes out of the body.) you are able to stop the victims Chakra Control compleatly. And that makes him unable to do any Justus, or regenerate chakra for a couple of hours.
