  In various unified extensions of the Minimal Supersymmetric Standard Model,
the Yukawa couplings of the third generation are predicted to be of the same
order. As a result, low energy measured mass ratios, require large ratios of
the standard model Higgs vacuum expectation values, corresponding to a large
value of the parameter $tan\beta$. We present analytic solutions for the Yukawa
couplings and the Higgs and third generation squark masses, in the case of
large top and bottom Yukawa couplings. We examine regions of these Yukawas
which give predictions for the top mass compatible with the present
experimentally determined top mass and provide useful approximate formulae for
the scalars. We discuss the implications on the Radiative Symmetry Breaking
mechanism and derive constraints on the undetermined initial conditions of the
scalars.
