Large corrections to the quark mass matrices at the supersymmetric threshold allow the theory to have identical Yukawa matrices in the superpotential. We demonstrate that up-down unification can take place in a moderate quark-squark alignment scenario with an average squark mass of the order 1TeV and with $\tan\beta\gt 15$.
