From: Relationship between gene duplicability and diversifiability in the topology of biochemical networks
Log-log plot of the numbers of protein-coding genes P (K) with duplicability K vs. K in the yeast S. cerevisiae and human. As described in Materials and Methods, duplicability K of a gene was calculated as BLAST hit count of its protein in an all-against-all BLAST, with a threshold BLAST E-value of 10−30. Linear relationships were observed, indicating power-law relationship between P(K) and K (P(K) ∝ K-α). And the slopes of the linear relationships – that is, the α values – were different between yeast and human. To better illustrate this difference, S. cerevisiae data points were shifted upward to overlap the leftmost data points of the two species.
