Abstract
In the nonsupersymmetric two-Higgs-doublet standard model, we find t-b -tau Yukawa unification consistent with the CERN LEP data, experimenta l values of m(b), m(tau), and m(t)=160-190 GeV at lower mass scales: M (C) similar or equal to 3X10(8)-3x10(9) GeV. We also show how such qua rk-lepton unification scales can be reconciled with SU(2)(L)xSU(2)(R)x SU(4)(C) intermediate breaking in SO(10) including threshold and gravi tational corrections.
