Query: The Globular Clusters of Dwarf Spheroidal Galaxies   The possibility that the Sagittarius dwarf spheroidal might have formed as a
Searle-Zinn fragment in the outer halo of the Galaxy is discussed. Arguments in
favor of this hypothesis are: (1) The luminosity distribution of globular
clusters in both Sagittarius and in the outer halo (Rgc > 80 kpc), appear to be
bimodal with peaks near MV ~ -5 and MV ~ -10, and (2) the globular clusters in
both Sgr, and in the outer halo, have a significantly larger age spread than do
the globulars in the inner halo of the Galaxy. However, a counter argument is
that only one of the four globulars associated with Sgr has the large
half-light diameter that is diagnostic of outer halo clusters. The absence of
globular clusters from all Local Group dwarf spheroidal galaxies fainter than
MV = -12 shows that their specific globular cluster frequency must be lower
than it is in the Fornax dwarf spheroidal. This result suggests that Fornax may
have had an unusual evolutionary history.
