Query: Dynamical Origin of Seesaw   In anomaly free gauged three-flavor SU(3)_f x SU(2)_L x U(1)_Y model of
Yanagida with fermion and gauge boson masses described by conveniently chosen
elementary scalar Higgs fields the neutrino mass matrix comes out in the seesaw
form. Following Yanagida's suggestion we demonstrate that no Higgs fields are
needed. Strong flavor gluon interactions themselves, treated in a separable
approximation, result in universally split lepton and quark masses calculated
in terms of a few parameters. While the realistic splitting of charged lepton
and quark masses requires the electroweak and QCD radiative corrections the
neutrino seesaw mass matrix comes out exact.
