Query: Predictions of $m_b/m_{\tau}$ and $m_t$ in an Asymptotically Non-Free
  Theory   We discuss an extention of the Minimal Supersymmetric Standard Model (MSSM)
with the 4th and anti-4th generations which have $SU(2)_L\times U(1)_Y$
invariant masses. Due to the the extra generations, all three running gauge
couplings become asymptotically non--free while preserving gauge coupling
unification at the GUT scale. We show that due to the asymptotically non--free
  character of the gauge couplings: (1) the top and bottom Yukawa couplings are
strongly focused onto infrared fixed points as they are evolved down in scale
making their values at $\mu=\mz$ insensitive to their initial values at
$\mu=\mgut$; (2) the model predicts $\R(\mz) \equiv Y_b/Y_\tau |_{\mu
=\mz}\approx 1.8$, which is consistent with the experimental value provided we
take the ratio of Yukawa couplings at the GUT scale to be $\R(\mgut) =
Y_b/Y_\tau |_{\mu = \mgut} = 1/3$; (3) the $t$ mass prediction comes out to be
$\mt\approx 180\,\GeV$ which is also consistent with experiment.
