Fig. 3From: Positive selection on the MHC class II DLA-DQA1 gene in golden jackals (Canis aureus) from their recent expansion range in Europe and its effect on their body mass indexEvolutionary relationships among DLA-DQA1 alleles in Canids, as represented by a median-joining network. For simplicity, allele designations are shown only by numbers (the correct full labels would include “DLA-DQA1*” prior to the respective allele number). Black circles represent median vectors. Alleles are colored according to their presence in species, and further information is given in Additional File 1: Table S1Back to article page
