Such sexual antagonism may be particularly acute in hermaphrodites, where both reproductive strategies are housed within a single individual. While previous models have focused on simultaneous hermaphroditism, we lack theory for how sexual antagonism may play out under sequential hermaphroditism, which has the additional complexities of age-structure. Here, we develop a formal theory of sexual antagonism in sequential hermaphrodites. First, we construct a general theoretical overview of the problem, then consider different types of sexually antagonistic and life-history trade-offs, under different modes of genetic inheritance (autosomal or cytoplasmic), and different forms of sequential hermaphroditism (protogynous, protoandrous or bidirectional). Finally, we provide a concrete illustration of these general patterns by developing a two-stage two-sex model, which yields conditions for both invasion of sexually antagonistic alleles and maintenance of sexually antagonistic polymorphisms.<\/jats:p>","DOI":"10.1098\/rspb.2023.2222","type":"journal-article","created":{"date-parts":[[2023,11,21]],"date-time":"2023-11-21T19:05:40Z","timestamp":1700593540000},"update-policy":"https:\/\/doi.org\/10.1098\/crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["Sexual antagonism in sequential hermaphrodites"],"prefix":"10.1098","volume":"290","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6378-5023","authenticated-orcid":true,"given":"Thomas J.","family":"Hitchcock","sequence":"first","affiliation":[{"name":"RIKEN Interdisciplinary Theoretical and Mathematical Sciences (iTHEMS), RIKEN, Wako, Saitama 351-0198, Japan"},{"name":"School of Biology, University of St Andrews, St Andrews, Fife KY16 9TH, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1304-3734","authenticated-orcid":true,"given":"Andy","family":"Gardner","sequence":"additional","affiliation":[{"name":"School of Biology, University of St Andrews, St Andrews, Fife KY16 9TH, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"175","published-online":{"date-parts":[[2023,11,22]]},"reference":[{"key":"e_1_3_8_2_2","volume-title":"The descent of man, and selection in relation to sex","author":"Darwin C","year":"1871","unstructured":"Darwin C. 1871 The descent of man, and selection in relation to sex, 1st edn.
