i$ and therefore must be analysed separately. An example of the origin of such zeros occurs in spontaneously broken Abelian theories through the so-called holomorphic zeros [@dudas]. In this case the symmetry breaking is through flavon field(s) carrying only one sign of charge (say negative) and then a net negative charge of the fermionic fields cannot be compensated with insertions of the flavon field because, due to the holomorphicity of the superpotential, the charged conjugated flavon can not be used. However the Kähler potential is non holomorphic and therefore these zeros can be filled after the transformation to the canonical basis.

As before, if we are only interested in the physical effects of this texture zero filling we can choose a convenient basis [@dudas]. Once more our choice of upper triangular matrices is especially simple. In a hierarchical texture we can have a texture zero in any position of the matrix except in $Y_{33}$ which is necessarily ${\mathcal{O}}(1).$ Although it is clear that the texture zeros can be filled in by the Kähler corrections we can immediately use the analysis presented above to show that physical measureables will not be affected by these corrections. The point, as is explicitly demonstrated
