Figure S3. Comparison of Pacific lamprey male and female genome assemblies and Sea Lamprey genome assembly positions (bp) of the total (blue) and outlier (orange) SNPs surveyed across rangewide Pacific lamprey collections on the following four pairs of homologous chromosomes that represent islands of divergence: a) Etr01 versus Pma Scaffold_00003, b) Etr02 versus Pma Scaffold_00006, c) Etr04 versus Pma Scaffold_00005, and d) Etr22 versus Pma Scaffold_00012 .
