Kekkei genkai (血継限界; 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.
Kekkei genkai and their related techniques cannot be taught to or copied by others. However, kekkei genkai can be given to others. Dōjutsu, or other kekkei genkai isolated to a single organ, can be transplanted into the body of another, as was done with transferring Obito's Sharingan to Kakashi. Use of these organs requires much more chakra than someone born with the kekkei genkai. Chakra elements can also be passed down to people outside of the clan, such as Yamato being subjected to DNA re-modification by Orochimaru who wanted to acquire the Wood Release kekkei genkai. However, Yamato's skill in using it is not nearly as powerful as the originator: Hashirama Senju, and the risk of such process was that Yamato was the only one of the sixty test subjects to survive.
Although kekkei genkai are usually genetically shared within a specific clan, sometimes it is unique to one person alone, and that even family relatives do not share it, such as the Wood Release and Shikotsumyaku. Yet other kekkei genkai seem to appear in individuals with no known relation, such as the Lava Release, which has appeared in ninja from Kirigakure, Iwagakure, and Kumogakure, while Magnet Release, which has appeared in ninja from both Kumogakure and Sunagakure.
List of Kekkei Genkai
Main article: Boil ReleaseBoil Release (沸遁, Futton; Viz "Vapour Style") is a combined nature transformation kekkei genkai made up of techniques that mix fire and water-based chakra to create gaseous materials in different properties and usages.
Main article: Byakugan The Byakugan (白眼; Literally meaning "White Eye", Meaning (Viz) "All Seeing White Eye") is the dōjutsu kekkei genkai of the Hyūga and Ōtsutsuki clans. Its power first appeared, alongside the Rinne Sharingan, in the oldest known ancestor of the Hyūga and Ōtsutsuki: Kaguya Ōtsutsuki. It has become known as one of the Three Great Dōjutsu (三大瞳術, San Daidōjutsu; Literally meaning "Three Great Eye Techniques"), along with the Sharingan, and the Rinnegan. This dōjutsu is manifested as very distinctive eyes, characterised by their enlarged and featureless white irides with no visible pupils. When the Byakugan is activated, the user's pupils become more distinct, and the veins near their temples bulge. It also appears that unlike the other two great dōjutsu, all members of the clan possess, and can use this kekkei genkai from birth, as opposed to needing to awaken, or else not inheriting it at all.The primary ability of the Byakugan gives the user a near 360º field of vision, except for one blind spot at the back of the neck above the first thoracic vertebra. Upon activation of the dōjutsu, the wielder is granted an automatic 50 metre field of vision around themselves which can be extended through training as Hinata Hyūga's range in Part II stretches to at least as far as 10 kilometres.The Byakugan is also able to see through solid objects and smokescreens, even through most barriers as only a particularly strong barrier such as the Four Black Fogs Formation is able to somewhat distort the Byakugan's perception. It can also differentiate between non-corporeal clones and see through techniques that would otherwise hide an opponent from normal sight. The dōjutsu also has the ability to follow high-speed movement.

When the technique is released, the form expands and surrounds the target. This nature allows the user to manipulate molecules, giving them the ability to disintegrate anything on a molecular level within the boundaries of the three-dimensional form.
Main article: Explosion ReleaseExplosion Release (爆遁, Bakuton; Viz "Explosive Style") is a combined chakra nature transformation kekkei genkai.

With the user normally having to witness or experience this first hand, Uchiha throughout history have killed those closest to them in order to expedite this process.It is distinguished from a normal Sharingan by its appearance, which changes the form of the tomoe seal. Unlike the Sharingan, the appearance of the Mangekyō Sharingan differs from user to user with all known wielders of the dōjutsu having eyes that resemble variations of pinwheels.
Ranmaru's Kekkei Genkai
Main article: Ranmaru's Kekkei Genkai Ranmaru possessed a dōjutsu kekkei genkai which, when activated, causes his eyes to glow red in colour. It grants him abilities such as penetrative vision as well as the ability to hinder other dōjutsu such as the Byakugan which his own dōjutsu has been likened to.This dōjutsu grants the wielder many abilities that include penetrating vision, disruption of other dōjutsu, and unique healing through life-force energy manipulation.With his kekkei genkai, Ranmaru has the ability to see and hear things from long distances. With this ability, Ranmaru was able penetrate the walls of his shack to view the outside world. Although the range of his kekkei genkai is similar to the range of the Byakugan, it actually has the ability to counter and negate that trait. His abilities also allow him to perform irresistible genjutsu, which can fool even the "all-seeing" Byakugan. Ranmaru's vision also lets him locate and track others by sensing chakra, picking up chakra from long distances, and noticing changes in an individual's chakra.

It is characterised by a ripple-like pattern which spreads over the eyeball, with light purple sclerae and irides, and also has another variant containing a pattern of six tomoe. It is said that in times when the world is in disorder, a person is sent down from the heavens to become either a "God of Creation" who will calm the world, or a "Destroyer" who will reduce everything to nothingness. The Rinnegan originated from Kaguya Ōtsutsuki's Rinne Sharingan, and was first truly manifested by her son, Hagoromo Ōtsutsuki, who came to be revered as the Sage of the Six Paths by using his dōjutsu to create the groundwork that brought forth all modern ninjutsu.
Ryūzetsu's Kekkei Genkai
Main article: Ryūzetsu's Kekkei GenkaiThis unnamed kekkei genkai apparently allows the user to perform Reincarnation Ninjutsu as it allowed Ryūzetsu to perform the Dragon Life Reincarnation technique.

Other details, such as whether it was common or rare and whether any other technique could be performed using it, are unknown.
Sakon and Ukon's Kekkei Genkai
Main article: Sakon and Ukon's Kekkei GenkaiSakon and Ukon's unnamed kekkei genkai gives them the unique ability to break their bodies down to a molecular level. The two brothers usually use this ability to share the same body but can also use it to merge with the bodies of others and destroy the host's cells from the inside. When Sakon is in need of assistance, Ukon can bring out some of his body parts to aid Sakon in blocking or attacking. Ukon's arms and legs can emerge from those of Sakon's to increase the force and quantity to his physical attacks.

Main article: SharinganThe Sharingan (写輪眼; Literally meaning "Copy Wheel Eye", Meaning (Viz) "Mirror Wheel Eye") is the dōjutsu kekkei genkai of the Uchiha clan that selectively appears in some of its members. While its progenitor was Kaguya Ōtsutsuki's Rinne Sharingan, its own individual form first manifested in Indra Ōtsutsuki, the earliest ancestor of the Uchiha clan, and later became regarded as one of the Three Great Dōjutsu (三大瞳術, San Daidōjutsu; Literally meaning "Three Great Eye Techniques"), along with the Byakugan and the Rinnegan. The Sharingan is also called "Heaven's Eye" (天眼, Tengan), because of the many abilities it grants the user. The Sharingan's abilities consist of two parts: the "Eye of Insight" (洞察眼, Dōsatsugan) and the "Eye of Hypnotism" (催眠眼, Saimingan). The first of the Sharingan's powers is being able to see chakra flow. The Sharingan itself gives colour to chakra, allowing the wielder to differentiate them. They are also able to tell if a person is under a genjutsu because the person's chakra flow would be irregular. The Sharingan's second-most prominent ability grants the user an incredible clarity of perception, allowing them to easily recognise genjutsu and different forms of chakra, though not to the same extent as the Byakugan.
Main article: ShikotsumyakuShikotsumyaku (屍骨脈; Literally meaning "Dead Bone Pulse", Meaning (Viz) "Macabre Bone Pulse") is a kekkei genkai which gives its wielder the ability to manipulate their own skeletal structure (their osteoblasts and osteoclasts). By infusing their calcium with chakra, they could manipulate the growth and properties of their bones to their liking. Kaguya Ōtsutsuki manifested a similar, albeit more lethal, ability to weaponise her bone structure from which Shikotsumyaku originates. This kekkei genkai is inherited into a rare few amongst Kaguya's descendants in the Kaguya clan, Kimimaro being the only other known inheritor of this power.

Wood and plants can be produced from any surface, including the user's own body, as the user's chakra is literally converted into a source of life. Wood Release Techniques (木遁の術, Mokuton no Jutsu) are commonly affiliated with the Snake seal.
The concept of special ninja techniques limited by bloodline inheritance may have been inspired in part by the works of Futaro Yamada, which strongly influenced later depictions of ninja in fiction. In particular, The Kōga Ninja Scrolls (甲賀忍法帖, Kōga Ninpōchō), published in 1959, featured a pair of warring ninja clans that, through selective breeding, had produced ninja with a variety of deformities, mutations, and special abilities, even dōjutsu.
- Kekkei genkai can be preserved through the creation of Human Puppets. This allows them to retain the special traits of the users when they were still alive.
- When a person is brought back to life via the Summoning: Impure World Reincarnation technique, they also retain any kekkei genkai they possessed before their death.
- A kekkei genkai should not be confused with hiden techniques. Hiden techniques are exclusive to a certain person or clan, but only because they have kept others from learning how to perform those techniques.
