Sex Bias and Maternal Contribution to Gene Expression Divergence in Drosophila Blastoderm Embryos. [PDF]
PLoS Genetics, 2015 Early embryogenesis is a unique developmental stage where genetic control of development is handed off from mother to zygote. Yet the contribution of this transition to the evolution of gene expression is poorly understood.

Mating system manipulation and the evolution of sex-biased gene expression in Drosophila
Nature Communications, 2017 Sexual selection on males is thought to favour male-biased gene expression. Here, Veltsos et al. experimentally evolve Drosophila pseudoobscura under different mating systems and, contrary to expectation, most often find masculinization of the ...

Evolution of Divergent Female Mating Preference in Response to Experimental Sexual Selection [PDF]
, 2014 Sexual selection is predicted to drive the coevolution of mating signals and preferences (mating traits) within populations, and could play a role in speciation if sexual isolation arises due to mating trait divergence between populations. However, few

The desaturase gene family : an evolutionary study of putative speciation genes in 12 species of Drosophila [PDF]
, 2012 The formation and persistence of species are the subject of much debate among biologists. Many species of Drosophila are behaviourally isolated, meaning that heterospecific individuals are not attracted to one another and do not interbreed.

Revealing posttranscriptional regulatory elements through network-level conservation. [PDF]
PLoS Computational Biology, 2005 We used network-level conservation between pairs of fly (Drosophila melanogaster/D. pseudoobscura) and worm (Caenorhabditis elegans/C. briggsae) genomes to detect highly conserved mRNA motifs in 3' untranslated regions.

Ancestral polymorphisms explain the role of chromosomal inversions in speciation.
PLoS Genetics, 2018 Understanding the role of chromosomal inversions in speciation is a fundamental problem in evolutionary genetics. Here, we perform a comprehensive reconstruction of the evolutionary histories of the chromosomal inversions in Drosophila persimilis and D ...

Krüppel Expression Levels Are Maintained through Compensatory Evolution of Shadow Enhancers
Cell Reports, 2015 Many developmental genes are controlled by shadow enhancers—pairs of enhancers that drive overlapping expression patterns. We hypothesized that compensatory evolution can maintain the total expression of a gene, while individual shadow enhancers diverge ...

Principles of genome evolution in the Drosophila melanogaster species group. [PDF]
, 2007 That closely related species often differ by chromosomal inversions was discovered by Sturtevant and Plunkett in 1926. Our knowledge of how these inversions originate is still very limited, although a prevailing view is that they are facilitated by ...

Shifting Balancing Selection Underlies an Inversion Cline in Eurasian Blackcap
Ecology and Evolution, Volume 16, Issue 6, June 2026.We investigated what factor contributes to a cline of a chromosomal inversion of the Eurasian blackcap, which differs from typical inversion clines maintained by divergent selection. Using a simulation‐based machine learning approach, we found that the inversion is under negative frequency‐dependent selection, and the optimal frequency is shifted ...
