Abstract: The main purpose of this paper is to investigate a class of genetic regulator model which was described by ordinary differential equations using center manifold theory and normal form theorem. Some sufficient conditions which guarantee the local stability and Hopf bifurcation are obtained,and some numerical simulation for justifying the theoretical results is also provided.

Key words: genetic regular model, equilibrium, stability, Hopf bifurcation
