Is it possible to predict the sign of the Matter-Antimatter Asymmetry in   the Universe?
  I investigate the possibility to define the sign of the leptonic asymmetry by the low energy parameters. It is shown that in the context of the minimal renormalizable SO(10) model the sign of the matter-antimatter asymmetry can be defined by the leptonic mixing and masses in the case of Type II see-saw.
