From: Relationship between gene duplicability and diversifiability in the topology of biochemical networks
Comparison of duplicability (K) distributions within the two groups of duplicate genes: genes in genetically antagonizing (GA) duplicate pairs (dashed line and white circle) vs. those in genetically complementing (GC) pairs (Solid line and black square). A: log(P(K)) vs. log(K) plot of genes whose BLAST hits enclose both proteins of a corresponding duplicate gene pair. B: log(P(K)) vs. log(K) plot of genes in corresponding group of duplicate gene pairs. The gene pairs were identified as described in Materials and Methods. The horizontal axis is the logarithms of gene duplicability K, which, as described in Materials and Methods, was calculated as BLAST hit count of a gene’s protein. Vertical axis is the logarithms of P(K). Linear regression lines, regression equations and R2 values of the regression are shown. In both panels, the GC gene data (black squares) fit well into power-law relationships, whereas the GA gene data (white circles) fit, if at all, poorly.
