By studying symmetric mass textures for the up and down quark sectors, and expanding in a small parameter [Formula presented] bounds are set on entries commonly assumed to vanish. Consequences of a 2+1 family structure which can result from horizontal symmetry are examined. Generalizing to squarks, we study suppression of flavor-changing neutral currents by mass degeneracy and/or small mixing angles.
