Genetic and Molecular Mechanisms in Animal Reproduction

Dear Colleagues,

Genetic and molecular mechanisms in animal reproduction involve processes like the formation of gametes, fertilization, gene regulation during development, and genetic imprinting, all of which ensure the continuation of species and create genetic diversity. Key molecular players include gene regulatory proteins that control cell differentiation and signaling pathways that regulate development, such as the Wnt, TGF-β, and MAPK pathways. These mechanisms are crucial for understanding reproduction and are used in modern breeding and conservation efforts.

Genetic and molecular processes

Gamete formation and fertilization: Meiosis creates haploid gametes, and their fusion during fertilization restores the diploid state in the offspring.

Gene regulation: Regulatory proteins and signaling pathways control gene expression patterns, which are essential for cell differentiation, sex determination, and overall embryonic development.

Genetic variation: Sexual reproduction, through the combination of genes from two parents and processes like crossing over, generates genetic diversity in offspring.

Genetic imprinting: In some cases, the expression of a gene depends on whether it was inherited from the mother or father.

Epigenetic changes: Environmental factors can cause epigenetic modifications that alter gene expression without changing the underlying DNA sequence, which can impact reproductive success.

This Special Issue, "Genetic and Molecular Mechanisms in Animal Reproduction", aims to compile a collection of cutting-edge research and insightful reviews that illuminate the complex regulatory networks controlling reproductive processes.

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 250 words) can be sent to the Editorial Office for assessment.

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.
