Kekkei genkai and related techniques can not be learned or copied by others. However, kekkei genkai may be passed on to third parties. Dōjutsu, kekkei genkai isolated to one organ, can be transplanted to the other person's body, as it was done with the Obito Sharingan transplant to the eye of Kakashi. The use of these organs requires more chakras than someone born from kekkei genkai. Elements of the chakra can be passed on to people outside the clan, just like the case of Yamato, who has undergone the modification of DNA by Orochimaru, gaining the ability to control the techniques of Freeing Wood. However, Yamato skills in use are not as powerful as in the case of their original user, Hashirama Senju, and the risk of success of this experiment is very low - only one of the sixty test objects survived. Kabuto Yakushiemu managed to gain access to Shikotsumyaku from the Kaguya clan and Kekkei genkai Sakon and Ukon by transplanting their DNA into their bodies, creating a clone of original owners, connected to his own body and using these abilities with the help of this clone. Some tailed beasts are known to have the kekkei genkai and can give them to their own suitable jinchūriki, for example the Release of the Shukaku Magnet and the Freeing of the Kokuō boiling water.
