A. Phylogenetic tree of evolutionary relationships of HMGN3a in 7 mammalian taxa using the Maximum Parsimony method. The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (500 replicates) is shown next to the branches. All positions containing gaps and missing data were eliminated from the dataset. B. Multiple sequence alignment of HMGN3a. Highlighted regions show substitutions in at least 1 of the 7 species. The alignment includes both the official bovine HMGN3a gene model (GLEAN_08006), in blue, and the bovine NCBI HMGN3a protein (NP_001029676.1). The insertion of alanine in the fifth exon of the bovine protein is marked in red.
