Digest: Evolution of a robust phenotype in Drosophila
1Schulich School of Medicine and Dentistry, University of Western Ontario, London, Canada.
Summary
Robust phenotypes, like body segmentation in Drosophila, evolve over evolutionary time. This study shows such traits develop through numerous incremental genetic modifications.
Area of Science:
- Evolutionary biology
- Developmental biology
- Genomics
Background:
- Investigating the evolution of robust phenotypes across a genus.
- Understanding the mechanisms driving the evolution of developmental traits.
Discussion:
- Segmentation along the head-to-tail axis in Drosophila is a developmentally robust phenotype.
- This phenotype has evolved over the evolutionary history of the Drosophila genus.
Key Insights:
- Evolutionary history of Drosophila reveals the emergence of robust phenotypes.
- The evolution of segmentation primarily occurred through numerous small genetic changes.
Outlook:
- Further research into the genetic basis of incremental evolutionary changes.
- Exploring whether similar evolutionary patterns apply to other robust phenotypes and genera.

02:27Background and Environment Affect Phenotype
7.3K
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

4.0K
The evolution of new genes is critical for speciation. Exon recombination, also known as exon shuffling or domain shuffling, is an important means of new gene formation. It is observed across vertebrates, invertebrates, and in some plants such as potatoes and sunflowers. During exon recombination, exons from the same or different genes recombine and produce new exon-intron combinations, which might evolve into new genes.
