Diversity of nucleotide positions. A. Each bar represents the nucleotide diversity of a single nucleotide position within the alignment of all cloned 185/333 genes. Green bars represent nucleotide positions within the intron. Gaps due to missing elements were excluded from the diversity calculations. B. Hypervariable positions within the 185/333 genes were identified using diversity analysis on clones belonging to cDNA-based sets (Table 5) with more than two members (94 genes total). Because sets had variable numbers of members, which artificially increases diversity for positions in sets with fewer members, each diversity score greater than 0 was assigned a value of 1. Each bar in the graph represents the number of sets (out of 8 total) that contained a polymorphism at the specific nucleotide position. Green bars indicate positions within the intron. Bars below the x-axis denote the borders between elements (cDNA-based alignment).
