Circos plot displaying centromere positions, Tcl-Mariner abundance, density of annotated protein coding genes, male and female Lake Trout (Salvelinus namaycush ) linkage maps and relationships between homeologs resulting from Ss4R. (A) Black boxes in the outside ring display the mean mapping positions (+/- 5 MB) for centromere associated RAD loci from Smith et al. (2020). (B) The second ring displays Z-transformed Tcl-Mariner repeat abundance in 5 megabase sliding windows with an offset of 100 kilobases. (C) The third ring displays the density of annotated genes in 5 megabase sliding windows with an offset of 100 kilobases. The fourth ring displays map distance (centimorgans) for male (red) and female (blue) linkage maps (y-axis) versus physical distance (x-axis) for each of the 42 chromosomes. Connections are drawn between syntenic blocks identified by SyMap v5 putatively resulting from the Salmonid specific autotetraploid event.

Comparison of BUSCO scores across multiple chromosome-level salmonid assemblies. Scores for the pre-duplication outgroup species (Northern Pike; Esox lucius ) are also included for comparison. Assemblies are listed top-to-bottom according to the total percentage of complete BUSCOs. Complete single-copy, complete duplicated, fragmented, and missing BUSCO percentages are delineated with green, blue, yellow, and red bars, respectively.
