    After analyzed the feasible solutions of N-queens problem, this paper brought forward the concept of morphological gene and rules to extract morphological genes. It connected dihedral group, morphological gene combination with equivalence class of queens position of N-queens problem, summarized the one eighth rule of N-queens problem, then analyzed the causes for attenuate of one eighth rule from two aspects of group and symmetry of morphological gene combination. It provided a new mentality for further deep research of N-queens problem, and is of reference value for studying highly effective algorithm for N-queens problem.
