Her Kekkei Mora seems to allow her to control various aspects of her body fro various effects and these effects separated and specialized over time through her descendents to the point that they are not Kekkei Morea but Genkai(thus bloodline LIMIT), as they have a limited form her powers in some way. That goes well with the idea that all Kekkei Genkai in the series along with all Yin and Yang based techniques are just fragments of her and Hagoromo's powers, basically all ninja abilities are degraded remnants of the original powers.
