Special Issue Information
Dear Colleagues,
From the early days of study of genetics and – with ever refined research tools – up to the present time, sex chromosomes have always been a source of fascination. At least three features set sex chromosomes apart from the rest of the genome and drive their unique evolution: the unusual pattern of transmission, the lack of recombination on sex-specific regions, and the absence of synapsis once the two sex chromosomes become divergent enough.
All these three features take place during meiosis, which makes this process the key component to understanding the evolution and differentiation of sex chromosomes. Surprisingly, however, the meiotic behaviour of sex chromosomes and the cellular context in which it happens have received little attention so far.
In this Special Issue, we aim to fill this gap by exploring the large diversity of sex chromosome systems and how the tightly choreographed process of meiosis copes with this. We hope that the table of contents will illustrate this diversity, and that multiple model systems, meiotic processes, and disciplines will be covered. We also seek to provide an overview of the advancements in our understanding of the meiotic contexts in which sex chromosomes arise and evolve.

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.
