The definition of a kekkei genkei is an ability that is possible through ones genes no? people who are born with two innate elements can preform advanced nature techniques, or able to manipulate their body's with their unique chakra for example the various Dojutsu and abilities like Shikotusmyaku. i do believe that yin/yang plays a part in these techniques as they are the basis to chakra. yin being the spirtual component or the "mind". Yang being the physical component or the "body".

Techniques such as Sharingan is a Yin Kekkei Genkai, I believe Shikotsumyaku is a Yang Kekkei Genkai, this is all speculation of course but i dont think it would be far fetched to believe that these techniques who are used by Shinobi with a distant blood relation to Kaguya, therefore being very unique individuals, would be able to mainpulate Yin and Yang Chakras into their Elemental or Non Elemental Kekkei Genkai's

Again, just a thought
