Special Issue Information
Dear Colleagues,
More than 30,000 species of fish have been identified, constituting the largest and most diverse group of vertebrates. Sex determination could be modulated both by genetic and external factors, and fish display the most versatile mechanisms among vertebrates. Unlike the conservation of the sex-determining gene SRY in mammals, a series of sex-determining genes have been identified in fish including dmrt1, dmy, amhy, sdY, gsdf etc. In sex differentiation, a range of the gonadal differentiation types have been described in fish, including gonochorism, sequential hermaphroditism that can initially mature either as males (protandrous) or females (protogynous), and simultaneous hermaphroditism. The diversity of sex determination and differentiation in fish provides an ideal opportunity to understand the formation and maintenance of sexes at the evolutionary level. In addition, studying sex determination and differentiation in fish is practical in aquaculture because of the potential benefits of monosex production, providing higher growth rates due to the prevailing sexual size dimorphism. Our Special Issue will mainly focus on omic and gene studies in both sex determination and differentiation in fish, including but not limited to the exploitation of gene resources through omic approaches, functional studies of genes, as well as genetic or epigenetic regulatory mechanisms. Research papers, short communications, and conceptual reviews are all welcome.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Genes is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
