Figure 1.
Distribution of the number of conserved genes within colinear regions of Arabidopsis and rice. The black, gray, and white histograms show the distribution of the blocks emerged by maximally 100%, 5%, and 1% chance, or 0%, 95%, and 99% significance levels, respectively. We propose to use the 99% significance level (i.e., maximally 1% probability to be generated by chance) as default setting.
