Figure 1From: The roles of segmental and tandem gene duplication in the evolution of large gene families in Arabidopsis thalianaSizes of gene families in A. thalianaApproximate gene family sizes were calculated using single-linkage clustering of BLASTP similarities below E-value thresholds of 10-10 (red), 10-20 (black), and 10-30 (blue). At the resolution of this graph, these lines follow nearly the same path. The curves follow a power law distribution. The best-fit power law equation for the 10-10 curve is indicated on the graph.Back to article page
