  We have studied mixing and masses of three left handed Majorana neutrinos in
the model, which assumes exactly degenerate neutrino masses at some "neutrino
unification" scale. Such a simple theoretical ansatz naturally leads to
quasidegenerate neutrinos. The neutrino mass splittings induced by
renormalization effects. In the model we found that the parameters of the
neutrino physics (neutrino mass spectrum, mixing angles and CP violation
phases) are strongly intercorrelated to each other. From these correlations we
got strong bounds on the parameters which could be checked in the oscillation
experiments.
