Sampling sites and MHC allele frequencies. 24 individuals were sampled from each of 16 sites spanning the range of mule deer (shown in light grey) between 1995 and 2005. The orange circles show the location of the sampling sites. Site details can be found in Additional file 2. The pie charts represent the proportion of different MHC alleles found in each population, with each allele’s respective color shown in the legend chart (1 = Odhe-DRB*01). The top 10 most common alleles are labeled in the legend with asterisks. Only the most common allele, Odhe-DRB*01, shown in the lightest blue, was found in every population. The shared allele between mule deer and white-tailed deer, Odvi-DRB*09, is shown in the darkest brown
