Query: Evolution of the Red Sequence in simulated galaxy groups   N--body + hydrodynamical simulations of formation and evolution of galaxy
groups in a LambdaCDM cosmology have been performed. The properties of the
galaxy populations in 12 groups are here discussed, with focus on the
colour-magnitude relation in both normal and fossil groups.
