We discuss the possibility of the asymmetry in D−/D+ production, from π− beams, being a direct consequence of the properties of the light quark fragmentation function into heavy mesons. The main features of the asymmetry, as a function of xF, are easily described. An integrated sum-rule for the D−,D+ difference, is presented. Predictions for the asymmetry, in B meson production, are given.
