  The quark mass matrices ansatze proposed by Fritzsch, Du-Xing and
Fukuyama-Nishiura in the framework of the general two Higgs doublet model are
studied. The corresponding Yukawa matrices in the flavor basis in the different
cases considered are discussed. The corresponding Cabbibo-Kobayashi-Maskawa
matrix elements are computed in all cases and compared with their experimental
values. The complex phases of the ansatze are taken into account and the CP
violating phase $\delta$ is computed. Finally, in order to observe the
influence of the different kind of textures of Yukawa coupling matrices
considered, some phenomenology of two body decays of the top quark, the
lightest Higgs boson and the charged Higgs boson is discussed.
