Description
We analyse the Yukawa matrices structure, $\widetilde{ \bf Y}_{ _{1,2} }^{q}$, by assuming a four-zero texture ansatz for their definition, in the frame of the general 2-Higgs Doublet Model. Explicit and exact expressions for $\widetilde{ \bf Y}_{ _{1,2} }^{q}$ are shown. Naturally, these expressions have a functional structure like to Cheng and Sher ansatz. Furthermore, we perform a $\chi^2$-fit based on current experimental data on the quark masses and the matrix ${ \bf V}_{\rm CKM }$, which give us results agreement with the bounds obtained taking into account constraints on Flavour Changing Neutral Currents reported in the literature.
