The evolution of X chromosomes after they stop recombining in males, but before they become hemizygous, has not been well explored theoretically. We use the diffusion approximation to infer substitution rates of beneficial and deleterious mutations under such a scenario. Our results show that selection is less efficient on diploid X loci than on autosomal and hemizygous X loci under a wide range of parameters. This “slower-X” effect is stronger for genes affecting primarily (or only) male fitness, and for sexually antagonistic genes. These unusual dynamics suggest that some of the peculiar features of X chromosomes, such as the differential accumulation of genes with sex-specific functions, may start arising earlier than previously appreciated."}],"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","short":"CC BY (4.0)"},"intvolume":"         7","keyword":["Genetics","Ecology","Evolution","Behavior and Systematics"],"year":"2023","isi":1,"external_id":{"pmid":["37065438"],"isi":["001021692200001"]},"ec_funded":1,"pmid":1,"date_published":"2023-02-01T00:00:00Z","acknowledgement":"We thank the Vicoso and Barton groups and ISTA Scientific Computing Unit.

Although they are known to have ZW chromosomes, these are not well characterized, and it is unclear whether they are shared across the clade. Furthermore, the underlying genetic architecture of the transmission of asexuality, which can occur when rare males mate with closely related sexual females, is not well understood. We produced a chromosome-level assembly for the sexual Eurasian species Artemia sinica and characterized in detail the pair of sex chromosomes of this species. We combined this new assembly with short-read genomic data for the sexual species Artemia sp. Kazakhstan and several asexual lineages of Artemia parthenogenetica, allowing us to perform an in-depth characterization of sex-chromosome evolution across the genus. We identified a small differentiated region of the ZW pair that is shared by all sexual and asexual lineages, supporting the shared ancestry of the sex chromosomes. We also inferred that recombination suppression has spread to larger sections of the chromosome independently in the American and Eurasian lineages. Finally, we took advantage of a rare male, which we backcrossed to sexual females, to explore the genetic basis of asexuality. Our results suggest that parthenogenesis is likely partly controlled by a locus on the Z chromosome, highlighting the interplay between sex determination and asexuality.","lang":"eng"}],"has_accepted_license":"1","file_date_updated":"2023-01-30T08:59:58Z","publication_identifier":{"issn":["1943-2631"]},"publication_status":"published","title":"ZW sex-chromosome evolution and contagious parthenogenesis in Artemia brine shrimp","oa_version":"Published Version","day":"01","scopus_import":"1","author":[{"orcid":"0000-0002-5328-7231","first_name":"Marwan N","full_name":"Elkrewi, Marwan N","id":"0B46FACA-A8E1-11E9-9BD3-79D1E5697425","last_name":"Elkrewi"},{"id":"5eba06f4-97d8-11ed-9f8f-d826ebdd9434","full_name":"Khauratovich, Uladzislava","last_name":"Khauratovich","first_name":"Uladzislava"},{"first_name":"Melissa A","orcid":"0000-0002-9752-7380","last_name":"Toups","id":"4E099E4E-F248-11E8-B48F-1D18A9856A87","full_name":"Toups, Melissa A"},{"last_name":"Bett","full_name":"Bett, Vincent K","id":"57854184-AAE0-11E9-8D04-98D6E5697425","first_name":"Vincent K"},{"first_name":"Andrea","full_name":"Mrnjavac, Andrea","id":"353FAC84-AE61-11E9-8BFC-00D3E5697425","last_name":"Mrnjavac"},{"full_name":"Macon, Ariana","id":"2A0848E2-F248-11E8-B48F-1D18A9856A87","last_name":"Macon","first_name":"Ariana"},{"first_name":"Christelle","orcid":"0000-0001-8441-5075","full_name":"Fraisse, Christelle","id":"32DF5794-F248-11E8-B48F-1D18A9856A87","last_name":"Fraisse"},{"first_name":"Luca","last_name":"Sax","full_name":"Sax, Luca","id":"701c5602-97d8-11ed-96b5-b52773c70189"},{"last_name":"Huylmans","full_name":"Huylmans, Ann K","id":"4C0A3874-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8871-4961","first_name":"Ann K"},{"first_name":"Francisco","last_name":"Hontoria","full_name":"Hontoria, Francisco"},{"first_name":"Beatriz","orcid":"0000-0002-4579-8306","last_name":"Vicoso","full_name":"Vicoso, Beatriz","id":"49E1C5C6-F248-11E8-B48F-1D18A9856A87"}],"date_created":"2023-01-16T09:56:10Z","article_type":"original","volume":222}]
