  We present the first study of rapidity gaps in e+e- annihilations using Z0
decays collected by the SLD experiment at SLAC. Our measured rapidity gap
spectra fall exponentially with increasing gap size over five decades, and we
observe no anomalous class of events containing large gaps. This supports the
interpretation of the large-gap events measured in pp and ep collisions in
terms of exchange of color-singlet objects. The presence of heavy flavors or
additional jets does not affect these conclusions.
