Or "Blodline limits"
Kekkei genkai-Literally meaning "a technique limited to inheritance by blood" or "Bloodline Limit") are abilities passed down genetically within specific clans. It's possible for a ninja to have more than one of these abilities. Kekkei genkai abilities that work via the user's eye are called dōjutsu. Other kekkei genkai include mixing one type of elemental chakra with another, creating a new one unique to the users, which is usually impossible for normal ninja, or other bodily manipulations that are usually unachievable by normal standards
