The elemental Kekkei Genkai are just combinations of the base elements. As Yamato put, there's no wood element. With the 5 base elements and Yin and Yang, she has all the powers. Combine this with the Rinne Sharingan and the Byakugan and she has technically all the powers. Rinnegan is something that has unique techniques, but the basic power over life and death (the Rinne part) is part of Kaguya's power.

Eventually that power of her diluted through the generations, and different people found different ways to use and abuse that power, creating new techniques and new kekkei genkai. But the source is the same. The Truthseeking Ball is the peak ability of Elemental kekkei genkai.
