Nesospiza MHCIIβ gene tree. Neighbour-Joining tree showing the three well supported Nesospiza MHCIIβ exon 2 allele clusters. Of the 23 alleles, 21 were found in the N. acunhae individuals on Inaccessible Island (Neso1-8, 1013, 1523), 14 in the N. wilkinsi and N. questi on Nightingale (Neso1, 3, 4, 7, 9, 11, 13–15, 17, 18, 20, 22, 23), and 7 in R. goughensis (Neso5, 9, 13–15, 17, 23). Bootstrap support <70% are not shown.
