Chromosome assignment
The current publicly available monarch genome used in this study
consists of 5,397 scaffolds with an N50 value of 715.6 kB. These
scaffolds were assigned to chromosomes using coverage-based chromosome
assignments produced by Mongue et al.(Mongue, Nguyen, Volenikova & Walters,
2017). FST , θπ ,Td andFSTZ outliers were calculated
for autosomes, Z-chromosome, and neo-Z chromosomes separately.
