The diffusion ratio is chosen to be the only bifurcation parameter in the analysis. Two dimensional Hexagonal Lattice is used as the geometrical argument in the construction of this analysis and the Fortran Programming Language is used to do the pattern simulations. The bifurcation diagrams are seen to be able to predict the morphology that is observed for the specific patterns.]]>Callahan, T.K. and E.
