G3: Genes, Genomes, Genetics, 2019 Meiotic crossing over ensures proper segregation of homologous chromosomes and generates genotypic diversity. Despite these functions, little is known about the genetic factors and population genetic forces involved in the evolution of recombination rate

Resource Partitioning Among Genotypes of Drosophila pseudoobscura [PDF]
Evolution, 1983 It is appealing to think that competition among genotypes within a population is essentially like that among species within a community. Important for the community are interspecific resource specialization and partitioning, which contribute to its species richness and stability.

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 ...

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.

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.

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 ...

Complex Evolutionary History of the Y Chromosome in Flies of the Drosophila obscura Species Group. [PDF]
, 2020 The Drosophila obscura species group shows dramatic variation in karyotype, including transitions among sex chromosomes. Members of the affinis and pseudoobscura subgroups contain a neo-X chromosome (a fusion of the X with an autosome), and ancestral Y ...

Inversion polymorphism in some natural populations of Drosophila pseudoobscura from central Mexico [PDF]
, 2007 Samples of D. pseudoobscura were taken in seventeen localities in Central Mexico inside the parallels 18o - 20o N, with the purpose of determine the chromosomal polymorphism in the third of the different populations of this species.
