We show, in a simple way, that the flavor asymmetry in the light-quark sea of the proton discovered by the New Muon Collaboration suggests also a large flavor asymmetry for the corresponding polarized distributions. This accounts for the violation of the Ellis-Jaffe proton sum rule reported by the European Muon Collaboration, but it implies no violation of the Ellis-Jaffe neutron sum rule, which seems confirmed from the very recent SLAC data.
