  1. Length = number of base pairs (bp); N = number of alleles when considering identical alleles across taxa separately; A = number of alleles across taxa; PIP = parsimony informative positions; VNP = variable nucleotide positions; R = transition/transversion bias; K2P distance = average mean evolutionary distance determined using the Kimura 2-parameter gamma model (K2P+Γ); AA = average mean poisson-corrected amino acid distance; dS = synonymous base pair substitution rate; dN = non-synonymous base pair substitution rate; Standard errors of estimates are shown in parentheses. *Includes the allele Eqbu-DQA*21, with a stop codon, while all other estimates exclude it.
