  We compare the branching ratios for $b\rightarrow s\gamma$ and
$\mu\rightarrow e\gamma$ in terms of constraining the parameter space in
supersymmetric SO(10) grand unification models where supersymmetry is broken
softly near the Planck scale by generationally symmetric operators. We observe
two general cases. One with small $\tan\beta =2$ and the other one with large
$\tan\beta$ having third generation Yukawa coupling unification at the GUT
scale. \newline\indent We show that for small $\tan\beta$ the branching ratio
constraints allow only a smaller region of parameter space for $\mu>0$ compared
to $\mu<0$ for gluino mass $\alt$ 500 GeV.
  With large $\tan\beta$, we find acceptable regions of parameter space with
$\left|\mu \right|\alt 1$ TeV only for $\mu<0$. The dominant constraint on
large $\tan\beta$ with $\mu >0$ parameter space is found to be given by the
$b\rightarrow s\gamma$ branching ratio, while for large $\tan\beta$ with $\mu
<0$ it is found to be given by the $\mu\rightarrow e\gamma$ branching ratio. In
many of these acceptable regions, we find that the $\mu\rightarrow e\gamma$
branching ratio is predicted to be within one order of magnitude of its current
experimental bound. We also show that the usually neglected gluino mediated
diagrams in $b\rightarrow s\gamma$ can not be ignored in some regions of
parameter space, especially for large $\tan\beta$ scenarios when the gluino
mass is near its lower experimental bound.
