We point out that the fragmentation of a strange quark into nucleons versus anti-nucleons is not necessarily identical D-p/s(z, Q(2)) not equal D-(p over bar)(z,Q(2)), even though the perturbative contributions from gluon splitting and evolution are p <-> (p) over bar symmetric. The observation of such asymmetries in the hadronization of strange and other heavy quarks can provide insight into the non-perturbative mechanisms underlying jet fragmentation in QCD.
