We discuss, in the framework of unified gauge theories, the possible connection between the CP-violating phase(s) (δB) responsible for matter-antimatter asymmetry and those phase(s) (δK responsible for low-energy CP-violating observables, like ɛ and ɛ' in the kaon system and the electric dipole moment of the neutron. We conclude, from the study of a variety of models with either intrinsic or spontaneous breaking of CP symmetry, that due to the existence of the SU(2)L × U(1) phase transition in general δB and δK bear no relation to each other, although they are both expressible in terms of the parameters characterizing the effective lagrangian of the theory.
