Fig. 1From: High functional allelic diversity and copy number in both MHC classes in the common buzzardMHC allele frequency and expression patterns in common buzzards. The proportion of individuals carrying each allele are shown for a) MHC-I exon 3 and for b) MHC-IIB exon 2. Colored bars indicate alleles that were shown to be expressed. Stars in b) indicate MHC-IIB alleles that have a 3Â bp deletionBack to article page
