Comparative analysis of the quantity, density and type of SNPs identified in the sterol biosynthesis pathway of <i>Trypanosoma cruzi</i>.

SNP counts marked with * indicate totals that do not result from the sum of synonymous + non-synonymous substitutions, in some cases because of the presence of two substitutions in the same codon, and in other cases, because some SNPs fall in the non-coding region of the gene.
