K-mer analysis of three Tokudaia species genomes. (a) T. osimensis (b) T. tokunoshimensis (c) T. muenninki. The estimated haploid genome sizes for T. osimensis, T. tokunoshimensis, and T. muenninki were 2,472.5 Mbp with 0.53% heterozygosity, 2,472.6 Mbp with 0.25% heterozygosity, and 3,362.6 Mbp with 0.45% heterozygosity, respectively. T. muenninki, with a genome size approximately 1 Gb larger than that of the other two species, shows consistency with a previous study demonstrating the presence of large heterochromatic blocks.
