Prdm9 Phylogenetic analyses and allele frequencies at different geographical scales. A PRDM9 phylogenetic analyses excluding hypervariable sites across all geographical regions, including several outgroups, from left to right Tree: Nucleotide Phylogeny of PRDM9 alleles allele: PRDM9 coding minisatellite allele colored as the translated variant from Fig. 1 pop: assigned population of individuals (dark blue): North Pacific, (light blue) North Atlantic, (light green) Antarctic Area IV, (dark green) Antarctic Area V, as well as Genome Reference alleles: (blue) Balaenoptera acutorostrata scammoni, (red) Balaenoptera bonaerensis and outgroups (pink) Tursiops Truncatus. # ZnFs: number of ZnFs − 1, + 3, + 6: Color coded Hypervariable positions of all repeats.
