The karyotype and identification of centromeres. a The chromosomes were classified and grouped according to the morphology. The chromosome numbers are named according to their homology with medaka chromosomes. b The total length and copy number of the top 10 abundant satellite repeats. The putative centromeric (Cen-524) and telomere-associated (Tel-190) repeats were highlighted in color. The full sequences of Cen-524 and Tel-190 are available in the Additional file 8: Table S7. c The distribution of Cen-524 and Tel-190 satellite sequences along the chromosomes. The chromosomes were grouped according to their morphological classification in a. Cen-524 has only one or zero peak while in some metacentric chromosomes Tel-190 has two peaks. In a few chromosomes (e.g., Chr4) the centromeric and subtelomeric satellite sequences may have not been assembled. d The FISH results of Cen-524 (red) and Tel-190 (green)
