Figure 2.

Allelic divergence observed in T. cruzi. Histogram of nucleotide diversity (π), showing the distribution of allelic variation in the analyzed data. Alignments (loci) meeting our criteria for good quality (see main text) and containing no more than 2 reference coding sequences from the CL-Brener genome, were used to calculate the nucleotide diversity values in the figure. The values of π were normalized over the effective length of the alignment (see Methods). For the histogram, the values were binned as shown in the x axis. Only values of π < 0.1, corresponding to 7,624 alignments (99.8%) were included in the graphic.
