Many of the ingredients are explored which are needed to develop a super-symmetric SO(10) x U(1)_F grand unified model based on the Yukawa structure ofa model previously constructed in collaboration with S. Nandi to explain thequark and lepton masses and mixings in a particular neutrino scenario. TheU(1)_F family symmetry can be made anomaly-free with the introduction of oneconjugate pair of SO(10)-singlet neutrinos with the same U(1)_F charge. Due toa plethora of conjugate pairs of supermultiplets, the model develops a Landausingularity within a factor of 1.5 above the GUT scale. With the imposition ofa Z_2 discrete symmetry and under certain conditions, all higgsino triplets canbe made superheavy while just one pair of higgsino doublets remains light andresults in mass matrix textures previously obtained from the bottom-upapproach. Diametrically opposite splitting of the first and third family scalarquark and lepton masses away from the second family ones results from thenonuniversal D-term contributions.Comment: 30 pages, LaTeX file, revised manuscript to appear in Z.
