The study of the intrinsic anisotropies of the extragalactic gamma-ray background is of cosmological importance. As the first step to investigate the anisotropies, new evolutionary results of the active galaxies are introduced and the fine-scale anisotropy is calculated because of the possible contribution from the AGN model. By use of Monte Carlo simulations, the fine-scale fluctuation patterns are discussed and it is proposed that these patterns or anisotropies form a unique test for the AGN generation mechanism. 53 refs.
