Sex-determining genes remain largely uncharacterized outside classical models in vertebrates and insects, leaving a gap in our understanding of their evolutionary emergence. The terrestrial isopod Armadillidium vulgare provides an excellent model for investigating this question, as it presents multiple genetic sex determinants. Some lineages possess a masculinizing dominant allele at a locus called the 'M gene',...
