Proceedings of the National Academy of Sciences of the United States of America, 2010 Polyandrous mating is common, but the benefits for females of polyandry remain controversial. To test whether mating with multiple males affects female fitness, we compared lifetime components of fitness of three experimental sets of Drosophila ...

Computer-Aided Automated Detection of Gene-Controlled Social Actions of Drosophila [PDF]
International Conference on Smart Cities at Cambridge 2018, 2019 Gene expression of social actions in Drosophilae has been attracting wide interest from biologists, medical scientists and psychologists. Gene-edited Drosophilae have been used as a test platform for experimental investigation. For example, Parkinson's genes can be embedded into a group of newly bred Drosophilae for research purpose.

Dimensionality-Reduction in the Drosophila Wing as Revealed by Landmark-Free Measure-ments of Phenotype [PDF]
arXiv, 2020 Organismal phenotypes emerge from a complex set of genotypic interactions. While technological advances in sequencing provide a quantitative description of an organism's genotype, characterization of an organism's physical phenotype lags far behind. Here, we relate genotype to the complex and multi-dimensional phenotype of an anatomical structure using

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 ...

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.

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.

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 ...

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,

On a Hyperbolic-Parabolic Parasitoid-Parasite System: Well Posedness and Control [PDF]
arXiv, 2020 We develop a time and space dependent predator-prey model. The predators' equation is a non local hyperbolic balance law, while the diffusion of prey obeys a parabolic equation, so that predators "hunt" for prey, while prey diffuse. A control term allows to describe the use of predators as parasitoids to limit the growth of prey-parasites.
