| Abstract: | The heterosis and the hybrid weaknesses are evaluated by fitness.A mathematical model is established to deduce the system of difference equations about the proportion of genotype（i.e.RR,Rr and rr） of panmictic population and the variation trend of the system is studied. |
| |
| Keywords: | panmictic population fitness mathematical model difference equation limit |
