The Elaborate Postural Display of Courting Drosophila persimilis Flies Produces Substrate-Borne Vibratory Signals. [PDF]
, 2016 Sexual selection has led to the evolution of extraordinary and elaborate male courtship behaviors across taxa, including mammals and birds, as well as some species of flies.

REPRODUCTIVE ISOLATION AS A CONSEQUENCE OF ADAPTIVE DIVERGENCE IN DROSOPHILA PSEUDOOBSCURA
Evolution; international journal of organic evolution, 1989 In an attempt to gain insight into the process of the development of reproductive isolation, eight populations of Drosophila pseudoobscura were ...

High frequency of microsatellites in Drosophila pseudoobscura.
Genes & Genetic Systems, 2000 Using 30,000 bp of anonymous sequence data, we note that dinucleotide repeat arrays appear to be much more common in Drosophila pseudoobscura than in D. melanogaster or D. simulans. Repeat arrays bearing five or more units are situated on average once every 3000 bp in D. pseudoobscura, and repeat arrays bearing ten or more units are situated on average

Male-biased genes are overrepresented among novel Drosophila pseudoobscura sex-biased genes [PDF]
, 2008 BACKGROUND: The origin of functional innovation is among the key questions in biology. Recently, it has been shown that new genes could arise from non-coding DNA and that such novel genes are often involved in male reproduction.

Evolutionary genomics of inversions in Drosophila pseudoobscura: Evidence for epistasis
Proceedings of the National Academy of Sciences of the United States of America, 2003 Drosophila pseudoobscura harbors a rich polymorphism for paracentric inversions on the third chromosome, and the clines in the inversion frequencies across the southwestern United States indicate that strong natural selection operates on them.

The Functions of the Multiproduct and Rapidly Evolving \u3cem\u3edec-1\u3c/em\u3e Eggshell Gene Are Conserved Between Evolutionarily Distant Species of Drosophila [PDF]
, 2001 The Drosophila dec-1 gene encodes multiple proteins that are required for female fertility and proper eggshell morphogenesis. Genetic and immunolocalization data suggest that the different DEC-1 proteins are functionally distinct.

Translocation of Y-linked genes to the dot chromosome in Drosophila pseudoobscura.
Molecular biology and evolution, 2010 One of the most striking cases of sex chromosome reorganization in Drosophila occurred in the lineage ancestral to Drosophila pseudoobscura, where there was a translocation of Y-linked genes to an autosome.

Collective mechanics of embryogenesis: Formation of ventral furrow in Drosophila [PDF]
arXiv, 2011 We propose a 2D mechanical model of the ventral furrow formation in Drosophila that is based on undifferentiated epithelial cells of identical properties whose energy resides in their membrane. Depending on the relative tensions of the apical, basal, and lateral sides, the minimal-energy states of the embryo cross-section includes circular, elliptical,

A comparative analysis of transcription factor expression during metazoan embryonic development [PDF]
, 2013 During embryonic development, a complex organism is formed from a single starting cell. These processes of growth and differentiation are driven by large transcriptional changes, which are following the expression and activity of transcription factors (TFs).

STUDIES ON “SEX–RATIO” IN DROSOPHILA PSEUDOOBSCURA. I. SELECTION AND “SEX–RATIO”
Evolution; international journal of organic evolution, 1948 In. several species of Drosophila, notably III the subgenus Sophophora, there exists a genetic condition known as "sexratio" which is inherited as though it were due to a sex-linked factor (sr) which causes the progeny of male carriers to consist almost ...
