Inversions in the third chromosome of wild races of Drosophila pseudoobscura, and their use in the study of the history of the species [PDF]
, 1936 Genetic studies showed several years ago that the third chromosomes of wild strains of Drosophila pseudoobscura often carry suppressors of crossing-over.

Mind the gap: upgrading genomes with Pacific Biosciences RS long-read sequencing technology. [PDF]
PLoS ONE, 2012 Many genomes have been sequenced to high-quality draft status using Sanger capillary electrophoresis and/or newer short-read sequence data and whole genome assembly techniques. However, even the best draft genomes contain gaps and other imperfections due

No evidence for learned mating discrimination in male
BMC Evolutionary Biology, 2006 Background Since females often pay a higher cost for heterospecific matings, mate discrimination and species recognition are driven primarily by female choice.

Acorns as Breeding Sites for \u3ci\u3eChymomyza Amoena\u3c/i\u3e (Loew) (Diptera: Drosophilidae) in Virginia and Michigan [PDF]
, 2017 Chymomyza amoena is the only chymomyzid fly emerging from white oak acorns in Virginia. An average of 2-3 adult flies emerged from a single acorn in July while emergence declined to 0.4 adults/acorns in September.

Temporalchanges in relative frequencies of third chromosome inversions of Drosophila pseudoobscura in Mexican populations [PDF]
, 2008 Variations in relative frequencies of third chromosome inversions during 1974-2000 in three populations of D. pseudoobscura from Mexico were analyzed. The general constitution of these populations is formed from ten up to 15 different inversions, been ...

How hot are drosophila hotspots? examining recombination rate variation and associations with nucleotide diversity, divergence, and maternal age in Drosophila pseudoobscura. [PDF]
PLoS ONE, 2013 Fine scale meiotic recombination maps have uncovered a large amount of variation in crossover rate across the genomes of many species, and such variation in mammalian and yeast genomes is concentrated to

Geographical changes in relative frequency of inversions in chromosome III of Drosophila pseudoobscura among natural populations from Mexico [PDF]
, 2009 Chromosomal polymorphism in natural populations of Drosophila pseudoobscura have been broadly studied in the USA but scarcely in Mexico where only about 60 localities have been analyzed.

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 ...
