Phylogenetic tree constructed for a 228 bp fragment of the second exon of MHC class I genes in the Scandinavian brown bear. Bayesian posterior probabilities above 70% are shown above branches. Alleles marked with “S” – are present in the southern Scandinavian population, marked with “N” are present in the northern Scandinavian population. Alleles marked with filled circle are expressed; marked with open circle are putatively not expressed. The other sequences used to generate the tree are: Ailuropoda melanoleuca: Aime-152 (EU162658.1), Aime-128*01 (EU162674.1), Aime-128*02 (EU162675.1), Aime-128*03 (EU162676.1), Aime-1906*01 (EU162662.1), Aime-1906*02 (EU162663.1), Aime-1906*03 (EU162664.1); Canis lupus: DLA-12 (NM_001014379.1), DLA-64 (NM_001014378.1), DLA-79 (NM_001020810.1), DLA-88*01 (AF100567.1), DLA-88*02 (AF100568.1), DLA-88*03 (AF100569.1), DLA-88*04 (AF100570.1), DLA-88*05 (AF100571.1); Felis catus: FLA-Aps (M27192.1), FLA-B*n03 (EU915357.1), FLA-B*n04 (EU915358.1), FLA-X10 (FCU0767388874.1); Phoca vitulina: PLA-A1 (U88874.1). Monodelphis domestica sequence: Modo (NM_001044223.1) was used to root the tree.
