Figure 6.
Classical DQA1, DQB1, and DRB1 alleles present on the 21 human haplotypes juxtaposed to a molecular phylogeny from the middle of the DQB1-DQA1 intergenic region. The phylogenetic tree is redrawn from Figure 5C with branches leading to haplotype groups A-E, as defined in the Figure 1 legend, labeled. Entries are marked N/A (“not available”) either because there is not a match to an established human allele—as was true for the gorilla and chimpanzee alleles—or insufficient data were available to establish a match.
