  We propose a renormalizable theory with minimal particle content and
symmetries, that successfully explains the number of Standard Model (SM)
fermion families, the SM fermion mass hierarchy, the tiny values for the light
active neutrino masses, the lepton and baryon asymmetry of the Universe, the
dark matter relic density as well as the muon and electron anomalous magnetic
moments. In the proposed model, the top quark and the exotic fermions do
acquire tree-level masses whereas the SM charged fermions lighter than the top
quark gain one-loop level masses. Besides that, the tiny masses for the light
active neutrino are generated from an inverse seesaw mechanism at one-loop
level.
