Summary
This study introduces a bioinformatic framework to identify sex-specific RNA transcripts. This method aids in understanding sex-based biological differences and developing genetic sexing tools for diverse applications.
Area of Science:
- Genomics
- Molecular Biology
- Bioinformatics
Background:
- Sex-specific transcripts reveal molecular and physiological differences between sexes.
- Accurate sex determination is crucial for agriculture, conservation, and entomology.
- Existing methods may lack efficiency or applicability across species.
Purpose of the Study:
- To develop a versatile bioinformatic framework for identifying sex-specific transcripts.
- To enable genetic sexing in eukaryotic species, with or without a reference genome.
- To support advancements in livestock management, ecological monitoring, and pest control.
Main Methods:
- Utilized RNA-sequencing (RNA-seq) data.
- Developed a computational framework for transcript analysis.
- Applied the framework to eukaryotic species, accommodating both reference-based and reference-free approaches.
Main Results:
- Successfully identified sex-specific transcripts using the developed framework.
- Demonstrated the framework's utility across different eukaryotic species.
- Provided a robust method for genetic sex determination.
Conclusions:
- The bioinformatic framework offers a powerful tool for discovering sex-specific transcripts.
- This approach facilitates the development of precise genetic sexing methods.
- The findings have broad implications for biological research and applied sciences.

The Ratio of X Chromosome to Autosomes

In most organisms, sex is determined by the ratio of X and Y chromosomes. However, in some organisms, such as Drosophila and C.elegans, sex is determined by the ratio of the number of X chromosomes to the number of sets of autosomes. The Y chromosome in Drosophila is active but does not determine sex. It contains genes responsible for the production of sperms in adult flies.

X and Y Chromosomes

Among mammals, the gender of an organism is determined by the sex chromosomes. Humans have two sex chromosomes, X and Y. Every human diploid cell has 22 pairs of autosomes and one pair of sex chromosomes. A human female has two X chromosomes, while a male has one X chromosome and one Y chromosome.
The germline cells such as egg and sperm cells carry only half the number of chromosomes, i.e., 22 autosomes and one sex chromosome. All eggs have an X chromosome, while sperm cells can carry an X or...

In animals, gender is determined by the number and type of sex chromosome. For example, human females have two X chromosomes, and males have one X and one Y chromosome, whereas C.elegans with one X chromosome is a male, and the one with two X chromosomes is a hermaphrodite.
In addition to sexual development, the X chromosome has genes involved in autosomal functions such as brain development and the immune system. Therefore, males and females with distinct numbers of X chromosomes will...

Genetic Screens
5.1K
Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which...
