Pattern selection in reaction-diffusion systems exhibiting bistability of homogeneous steady states is discussed. In agreement with recent experimental results, we obtain new bifurcation diagrams involving large-amplitude structures that arise from the coupling of the spatial critical modes with a quasi-neutral homogeneous mode.
