Genetic Screens

5.8K
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...

Evolutionary Relationships through Genome Comparisons

7.2K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

The Ratio of X Chromosome to Autosomes02:45

The Ratio of X Chromosome to Autosomes

10.0K
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.  
Normal male Drosophila has a ratio of one X chromosome to two sets of autosomes. In contrast, normal female...

Genome-wide Association Studies-GWAS

16.5K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Area of Science:

  • Genomics
  • Comparative genomics
  • Functional genomics

Background:

  • Comparative genomics leverages well-annotated genomes (e.g., mouse) to infer gene function in less-studied organisms (e.g., Burmese python).
  • Understanding gene-phenotype relationships is crucial for inferring physiological roles.

Purpose of the Study:

  • To functionally annotate Python bivittatus genes related to sperm phenotypes using comparative genomics.
  • To establish a high-resolution genomic framework for studying reptile spermatogenesis, fertility, and reproduction.

Main Methods:

  • Employed comparative genomics to analyze Python bivittatus genes encoding sperm-associated proteins.
  • Identified gene-phenotype relationships and associated them with Gene Ontology (GO) terms.
  • Visualized functional annotation data using a semantic scatter plot.

Main Results:

  • Identified 129 gene-phenotype relationships in Python bivittatus linked to 10 specific sperm phenotypes.
  • Discovered subsets of python genes associated with specific GO annotation terms.
  • Generated a functional annotation of the Burmese python genome relevant to reproductive biology.

Conclusions:

  • The newly annotated Python bivittatus genome resources provide a valuable framework for investigating reptile reproductive biology.
  • Applications include developing genetic diagnostics for reptile fertility, enhancing assisted reproduction for conservation, and targeting invasive reptile fertility.
  • Further enhancement of reptile genomic resources will increase their utility for scientific and applied purposes.
