Abstract
We discuss the possibility of the asymmetry in D-/D+ production from $\pi^-$ 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+ multiplicity difference is presented. Predictions for the asymmetry in B meson production are given.
