  We study the consequences of assuming that the mass scale $\Delta_{odot}$
corresponding to the solar neutrino oscillations and mixing angle $U_{e3}$
corresponding to the electron neutrino oscillation at CHOOZ are radiatively
generated through the standard electroweak gauge interactions. All the leptonic
mass matrices having zero $\Delta_{odot}$ and $U_{e3}$ at a high scale lead to
a unique low energy value for the $\Delta_{odot}$ which is determined by the
(known) size of the radiative corrections, solar and the atmospheric mixing
angle and the Majorana mass of the neutrino observed in neutrinoless double
beta decay. This prediction leads to the following consequences: ($i$) The MSSM
radiative corrections generate only the dark side of the solar neutrino
solutions. ($ii$) The inverted mass hierarchy ($m,-m,0$) at the high scale
fails in generating the LMA solution but it can lead to the LOW or vacuum
solutions. ($iii$) The $\Delta_{odot}$ generated in models with maximal solar
mixing at a high scale is zero to the lowest order in the radiative parameter.
It tends to get suppressed as a result of this and lies in the vacuum region.
We discuss specific textures which can lead to the LMA solution in the present
framework and provide a gauge theoretical realization of this in the context of
the seesaw model.
