dσ/dΩ for e+e→hX is calculated for the most general electron-quark-heavy boson ("t-channel") or positron-quark-heavy boson ("u-channel") interaction together with the electrodynamic contribution using the naive parton model with collinear quark fragmentation to hadrons. No single S, V, T, A, or P exchange gives isotropic dσ/dΩ V and A exchanges give closest to isotropic. Two linear combinations which give isotropic contributions from the direct quark-lepton interaction are given.
