Monofunctional circuits typically have latent phenotypes. Each data point depicts the proportion and number of monofunctional circuits with f latent phenotypes. The white and black circles correspond to an identity (e.g., 〈0,0,0〉↦〈0,0,0〉) and transition (e.g., 〈0,0,0〉↦〈0,0,1〉) mapping, respectively. The genotype set of each identity mapping comprises 2,097,152 genotypes, while that of each transition mapping comprises 672,592 genotypes [35]. All 8 identity and 56 transition monofunctions exhibit a pattern exactly identical to that of the white and black circles, respectively, shown in the figure. The lines are provided as visual guides. Note the logarithmic scale of the y-axis.
