Query: Ansatz for Quark, Charged Lepton, and Neutrino Masses in SUSY GUTS   We extend a fermion mass matrix Ansatz by Giuduce to include neutrino masses.
The previous predictions are maintained. With two additional parameters, a
large Majorana neutrino mass and a hierarchy factor, we have seven {\it
further} low energy predictions: the masses of the neutrinos, the mixing angles
and the phase in the leptonic sector. We choose a reasonable hierarchy of
Majorana masses and fit the overall mass scale according to a solution of the
solar neutrino problem via the MSW mechanism, which is in agreement with the
$^{37}Cl$, Kamiokande, and GALLEX data. We then also obtain a cosmologically
interesting tau-neutrino mass.
