  We consider a simple way for solving the flavor question by embedding the
three-familiy Standard Model in a semisimple gauge group extending minimally
the weak isospin factor. Quantum chiral anomalies between families of fermions
cancel with a matching of the number of families and the number of color
degrees of freedom. Our demonstration shows how the theory leads to
determination of families structure when the Standard Model is the input at low
energies. The new physics is limited to start below a few TeVs within the reach
of the next generation colliders.
