Dear Dmitry,
My guess is that taking into account strong cross section for nucleon-antinucleon annihilation (and for charged pions annihilation to neutral pion pairs) your frozen our concentration will be so small that the rate of nuclear reactions and of recombination (for which you should also calculate frozen out concentration for mirror electron-positron pairs) will be much smaller, than the rate of expansion in the corresponding periods, as well as their contribution into the total density will be not sufficient to provide matter dominated stage and development of gravitational instability (growth of small density fulctuations)
We have no time to continue work on your text, soi you are admitted to exam, provided that you prepare these calculations as addtional questions to your ticket.
