Evidence that natural selection on codon usage in Drosophila pseudoobscura varies across codons. [PDF]
G3 (Bethesda), 2014 Like other species of Drosophila, Drosophila pseudoobscura has a distinct bias toward the usage of C- and G-ending codons. Previous studies have indicated that this bias is due, at least in part, to natural selection.

Molecular population genetics of inversion breakpoint regions in Drosophila pseudoobscura. [PDF]
G3 (Bethesda), 2013 Paracentric inversions in populations can have a profound effect on the pattern and organization of nucleotide variability along a chromosome. Regions near inversion breakpoints are expected to have greater levels of differentiation because of reduced ...

Conserved genomic organisation of Group B Sox genes in insects. [PDF]
BMC Genetics, 2005 Background Sox domain containing genes are important metazoan transcriptional regulators implicated in a wide rage of developmental processes. The vertebrate B subgroup contains the Sox1, Sox2 and Sox3 genes that have early functions in neural ...

Testes Proteases Expression and Hybrid Male Sterility Between Subspecies of Drosophila pseudoobscura [PDF]
G3: Genes, Genomes, Genetics, 2019 Hybrid male sterility (HMS) is a form of postmating postzygotic isolation among closely related species that can act as an effective barrier to gene flow.

Modifiers and 'Sex Ratio' in Drosophila pseudoobscura [PDF]
Evolution, 1978 The "sex ratio" (SR) inversions found on the X chromosomes of several Drosophila species cause males to produce progeny consisting almost entirely of females; of those few sons produced some are XY and some are XO (Sturtevant and Dobzhansky, 1936). The XO sons are sterile.

Chemical signals and social structures strengthen sexual isolation in Drosophila pseudoobscura [PDF]
Communications BiologySpecies that coexist in hybrid zones sexually isolate through reproductive character displacement, a mechanism that favours divergence between species. In Drosophila, behavioural and physiological traits discourage heterospecific mating between species ...

Extensive divergence of transcription factor binding in Drosophila embryos with highly conserved gene expression. [PDF]
PLoS Genetics, 2013 To better characterize how variation in regulatory sequences drives divergence in gene expression, we undertook a systematic study of transcription factor binding and gene expression in blastoderm embryos of four species, which sample much of the ...

Can patterns of chromosome inversions in Drosophila pseudoobscura predict polyandry across a geographical cline? [PDF]
Ecol Evol, 2014 Journal ArticleFemale multiple mating, known as polyandry, is ubiquitous and occurs in a wide variety of taxa. Polyandry varies greatly from species in which females mate with one or two males in their lifetime to species in which females may mate with ...

Epistasis among Drosophila persimilis factors conferring hybrid male sterility with D. pseudoobscura bogotana. [PDF]
PLoS ONE, 2010 The Bateson-Dobzhansky-Muller model posits that hybrid incompatibilities result from genetic changes that accumulate during population divergence.
