However, in most lineages outside of the division Ditrysia, as well as in the sister order Trichoptera, females lack a W chromosome. The W is therefore thought to have been acquired secondarily. Here we compare the genomes of three Lepidoptera species (one Dytrisia and two non-Dytrisia) to test three models accounting for the origin of the W: (1) a Z-autosome fusion; (2) a sex chromosome turnover; and (3) a non-canonical mechanism (e.g., through the recruitment of a B chromosome). We show that the gene content of the Z is highly conserved across Lepidoptera (rejecting a sex chromosome turnover) and that very few genes moved onto the Z in the common ancestor of the Ditrysia (arguing against a Z-autosome fusion). Our comparative genomics analysis therefore supports the secondary acquisition of the Lepidoptera W by a non-canonical mechanism, and it confirms the extreme stability of well-differentiated sex chromosomes."}],"citation":{"mla":"Fraisse, Christelle, et al. “The Deep Conservation of the Lepidoptera Z Chromosome Suggests a Non Canonical Origin of the W.” <i>Nature Communications</i>, vol. 8, no. 1, 1486, Nature Publishing Group, 2017, doi:<a href=\"https://doi.org/10.1038/s41467-017-01663-5\">10.1038/s41467-017-01663-5</a>.","ama":"Fraisse C, Picard MAL, Vicoso B.
