  The trend of [Mn/Fe] in the Galactic bulge follows the solar-neighborhood
relation, but most stars in the Sagittarius dwarf spheroidal galaxy show
[Mn/Fe] deficient by approximately 0.2 dex. This leads us to conclude that the
Mn yields from both type Ia and type II SNe are metallicity-dependent. Our
observations militate against the idea, suggested by Gratton, that Mn is
over-produced by type Ia SNe, relative to type II SNe. We predict Mn/Fe ratios,
lower than the solar neighborhood relation, for the younger populations of
nearly all dwarf galaxies, and that Mn/Fe ratios may be useful for tracing the
accretion of low-mass satellites into the Milky Way.
