It has long been observed that an average of inclusive electron scattering cross section data in the resonance region is close to that in the deeply inelastic region. On the other hand, our understanding of the data is in terms of hadronic degrees of freedom (mesons, baryons) in the resonance region, but in terms of quarks and gluons in the deeply inelastic scattering region. Thus the close relationship between the data in these two very different energy regions must reflect the Quark-Hadron Duality. Recent data from Jefferson Laboratory have provided new opportunities for exploring this subject in great detail. In this talk, I will review the theoretical work on this subject and report on our recent work including the first predictions on Quark-Hadron Duality in neutrino-induced reactions and parity-violating asymmetry.
