Principal component analysis of sampled genotypes in V(n). The figure shows the first two principal components for the randomly sampled genotypes that are viable in the glucose chemical environment with n equal to that of E. coli. The horizontal axis shows the first principal component, and the vertical axis shows the second principal component. The figure additionally shows in red the E. coli genotype in this space. The first two components account for less than 0.8% of the variance in the data. The analysis suggests that there are no multiple clusters.
