Neighbor-joining phylogenies among red fox DRB1 alleles and DRB1 alleles from other canids accessed from GenBank. Accession numbers are given with taxon name, and allele designations are as stated in the accession. Numbers above nodes are percentage support from 10,000 bootstrap replicates. The blocks to the right show the amino acid associated with each taxon at selected sites identified by HyPhy, as discussed in the text. These correspond to sites 64 (a) and 30, 56, and 67 (b) in Fig. 2b. a Vulpes only phylogeny: Vula = Vulpes lagopus and Vuvu DRB1-Vuvu DRB8 designate the Vulpes vulpes alleles. b Vulpes, Urocyon, and Canis lupus comprehensive phylogeny. Urli = Urocyon littoralis and Calu = Canis lupus. Due to the very large number of alleles available from Canis sp., Canis lupus was selected here to represent the lineage
