We derive a relation between the theoretical quark-production asymmetries and measured jet asymmetries in e/sup +/e/sup -/ annihilation using simple parameters obtained from quark-fragmentation models. We show that with a suitable choice of jet criteria one should be able to observe sizable effects in spite of problems caused by quark misidentification. Mass effects near new-quark thresholds and the shapes of quark asymmetries for different flavors are discussed.
