Scope and policy

Genetics and Molecular Biology (formerly named Revista Brasileira de Genética/Brazilian Journal of Genetics - ISSN 0100-8455) is published by the Sociedade Brasileira de Genética (Brazilian Society of Genetics).

The Journal considers contributions that present the results of original research in genetics, evolution and related scientific disciplines. Manuscripts presenting methods and applications only, without an analysis of genetic data, will not be considered.

Although Genetics and Molecular Biology is an official publication of the Brazilian Society of Genetics, contributors are not required to be members of the Society.

It is a fundamental condition that submitted manuscripts have not been and will not be published elsewhere. With the acceptance of a manuscript for publication, the publishers acquire full and exclusive copyright for all languages and countries.

Manuscripts considered in conformity with the scope of the journal, judged by the Editor in conjunction with the Editorial Board, are reviewed by the Associate Editor and two or more external reviewers. Acceptance by the Editor is based on the quality of the work as substantial contribution to the field and on the overall presentation of the manuscript.

Genetics and Molecular Biology follows and Open-Access policy. Articles are made available in full content at SciELO. Back issues dating to 1998 are available through this site.

Back issues of the earlier titles (Brazilian Journal of Genetics and Revista Brasileira de Genética) are hosted at the journal's own site:

Articles published since 2009 are also indexed at PubMed Central, and there available as a full text version.

The official abbreviation for Genetics and Molecular Biology is Genet. Mol. Biol.


Submission of papers

There is a publication charge for manuscripts once they are accepted. For price information, exemptions and waiver policies, please consult the journal homepage

1. Manuscripts must be submitted through a Scholar One submission platform hosted at:

The cover letter should be addressed to:

  • Editor-in-Chief, Genetics and Molecular Biology

2. For submission the following instructions must be observed:

a) The manuscript that must be submitted by the Corresponding Author. This is the person who will also check the page proofs, and arranges for the payment that may incur during the editorial process.

b) Entering the following metadata is required: (i) the manuscript title, (ii) a short running title (max. 35 characters), (iii) the Abstract, and (iv) up to five keywords. All these items must be exactly the same as those figuring in the first two pages of the manuscript file. Furthermore, a cover letter addressed to the Editor is required. It must be edited by the corresponding author inserted within the reserved data field

Special attention should be given to the structuring of the manuscript and correct language usage. These are important factors in the smooth running of the editorial and peer-review process, and can result in faster publication.

3. Categories of Contribution
3.1. Research Articles

Manuscripts must be written in English in double-spaced, 12-point type throughout; marked with consecutive line and page numbers, beginning with the cover page.

The following elements must start on a new page and be ordered as they are listed below:

a) The title page must contain: a concise and informative title; the authors' names (first name at full length); the authors' institutional affiliation, including department, institution, city, state or province and country; different affiliations indicated with superscript Arabic numbers; a short running title of about 35 characters, including spaces; up to five key words; the corresponding author's name, postal address, phone and fax numbers and email address.

b) The Abstract must be a single paragraph that does not exceed 200 words and summarizes the main results and conclusions of the study. It should not contain references.

c) The text must be as succinct as possible. Text citations: articles should be referred to by authors' surnames and date of publication; citations with two authors must include both names; in citations with three or more authors, name the first author and use et al. List two or more references in the same citation in chronological order, separated by semi-colons. When two or more works in a citation were published in the same year, list them alphabetically by the first author surname. For two or more works by the same author(s) in a citation, list them chronologically, with the years separated by commas. (Example: Freire-Maia et al., 1966a, 1966b, 2000). Only articles that are published or in press should be cited. In the case of personal communications or unpublished results, all contributors must be listed by initials and last name (et al. should not be used). Numbers: In the text, numbers nine or less must be written out except as part of a date, a fraction or decimal, a percentage, or a unit of measurement. Use Arabic numerals for numbers larger than nine. Binomial Names: Latin names of genera, species and infraspecific taxa must be printed in italics; names of orders and families should appear in the Title and also when first mentioned in the text. URLs for programs, data or other sources should be listed in the Internet Resources Section, immediately after the References Section, not in the text.

The text includes the following elements:

Introduction - Description of the background that led to the study.

Material (or Subjects) and Methods - Details relevant to the conduct of the study. Statistical methods should be explained at the end of this section.

Results - Undue repetition in text and tables should be avoided. Comment on significance of results is appropriate but broader discussion should be part of the Discussion section.

Discussion - The findings of the study should be placed in context of relevant published data. Ideas presented in other publications should not be discussed solely to make an exhaustive presentation.

Some manuscripts may require different formats appropriate to their content.

d) The Acknowledgments must be a single paragraph that immediately follows the discussion and includes references to grant support.

e) The References Section: references must be ordered alphabetically by the first author surname; references with the same first author should be ordered as follows: first, as single author in chronological order; next, with only one more co-author in alphabetical order by the second author; and finally followed by references with more than two co-authors, in chronological order, independent of the second author surnames. In references with more than 10 authors only the first ten should be listed, followed by et al. Use standard abbreviations for journal titles as suggested byNCBI (

Only articles that are published or in press should be included in this section. Works submitted for publication but not yet accepted, personal communications and unpublished data must be cited within the text. "Personal communication" refers to individuals other than the authors of the manuscript being submitted; "unpublished data" refers to data produced by at least one of the authors of the manuscript being submitted. Works of restricted circulation (e.g., theses not available in public databases, congress abstracts not published in regular journals or public databases) should not be listed in this section.

g) Tables must be in Word format prepared with table tool (do not use space bar or tabulator). A concise title should be provided above the table. Tables must be numbered consecutively in Arabic numerals. Each column must have a title in the box head. Footnotes typed directly below the table should be indicated in lowercase superscript numbers. Tables that are to appear in the printed version must be saved in Word format and not as figures, so that they can later be fitted during typesetting. Each table must be saved and uploaded as a separate file.

h) Figures must be numbered consecutively in Arabic numerals. Images should be in TIFF or JPEG format and provided in separate files. Identify each illustration by the first author name and the number of the respective figure. Figures in Word, PowerPoint or Excel format cannot be published. Only sequence data can be presented in Word format. Journal quality reproduction will require grayscale resolution yielding 300 dpi, color figures should be at 600 dpi. These resolutions refer to the output size of the file; if it is anticipated that images will be enlarged or reduced, the resolutions should be adjusted accordingly. Figures composed of several elements should be sent as a single panel, obeying the print size definitions of the journal (single or two columns width). Scanned figures should not be submitted. Color illustrations are accepted.

Each figure/panel must be saved and uploaded as a separate file. When uploading, identify each illustration by the first author name and the number of the respective figure.

Figure legends must be included in the main text file and should be typed on a new page that immediately follows the tables.

i) Nomenclature should adhere to current international standards.

j) Sequences may appear in text or in figure. DNA, RNA and protein sequences equal to or greater than 50 units must be entered into public databases and accession numbers must be provided upon acceptance of the article. Failure to do so will delay publication.

k) Data access: reference should be made to availability of detailed data and materials used for reported studies.

l) Ethical issues: reports of experiments on live vertebrates must include a statement that the institutional review board approved the work and the protocol number must be provided. For experiments involving human subjects, authors must also include a statement that informed consent was obtained from all subjects. If photos or any other identifiable data are included, a copy of the signed consent must accompany the manuscript.

m) Supplementary Material: Data that the authors consider of importance for completeness of a study, but which are too extensive to be included in the published version, can be submitted as Supplementary Material. This material will be made available together with the electronic version. In case a manuscript contains such material, it should be appropriately identified within the text file. Supplementary material in tables should be identified as Table S1, Table S2, etc., in case of figures, they should be named accordingly, Figure S1, Figure S2. In addition, a list of this material should be presented at the end of the manuscript text file, containing the following statement: Supplementary material - the following online material is available for this article:

- Table S1 < short title >
- Figure S1 - < short title >
This material is available as part of the online article from

  • should be 15 or fewer typed pages in double spaced 12-point type, including literature cited;
  • should include an Abstract;
  • but no further subdivision, with introduction, material and methods, results and discussion; all in a single section and without headers.
  • up to four items (tables and/or figures) may be submitted;
    Note: The title page, abstract and reference section format is that of a full-length Research Article. For Supplementary Material see instructions in item 3.1.m
