  We study the predictions for M_top, tan(beta) and V_cb in a popular texture
ansatze for the fermion mass matrices. We do this both for the Minimal
Supersymmetric Standard Model (MSSM) and for the simplest model (MSSM-BRpV)
where a bilinear R-Parity violating term is added to the superpotential. We
find that taking the experimental values for M_top and V_cb at 99 % C.L. and
the GUT relations h_b=h_tau and (V_cb)^2=h_c/h_t within 5 %, the large
tan(beta) solution, characteristic in the MSSM with bottom--tau unification,
becomes disallowed. In contrast the corresponding allowed region for the
MSSM-BRpV is slightly larger. We also find that important modifications occur
if we relax the texture conditions at the GUT scale. For example, if the GUT
relations are imposed at 40 %, the large tan(beta) branch in the MSSM becomes
fully allowed. In addition, in MSSM-BRpV the whole tan(beta)-M_top plane become
allowed, finding unification at any value of tan(beta).
