Genomes for a cellular developmental system include some form of gene regulation. As such, evolution searches for genomes that are evaluated by properties emerging in the interplay between the genome and the emerging phenotype. In this paper an experimental approach is taken to show that information from this iterative process can be used to provide the evaluation process with information of the emerging phenotype. Experiments show that evaluation of gene regulation network can indirectly give information on growth, differentiation and self-regulation in the phenotype. An experiment exploiting these properties towards development of stable self-regulation functional circuits is presented. All experiments are carried out using hardware cellular development and phenotypes that emerge in hardware.
