The spontaneous mutation rate of Drosophila pseudoobscura
G3, 2021 The spontaneous mutation rate is a very variable trait that is subject to drift, selection and is sometimes highly plastic. Consequently, its variation between close species, or even between populations from the same species, can be very large.

Evolution; international journal of organic evolution, 2021 By shaping meiotic recombination, chromosomal inversions can influence genetic exchange between hybridizing species. Despite the recognized importance of inversions in evolutionary processes such as divergence and speciation, teasing apart the effects of

Genetics, 2020 The Drosophila pseudoobscura Sex-Ratio (SR) chromosome was one of the first-discovered segregation distorter chromosomes. Despite being a historically significant and well-studied segregation distortion system, the mechanisms allowing for the long-term...

Genetics, 2004 The genetic study of diverging, closely related populations is required for basic questions on demography and speciation, as well as for biodiversity and conservation research.

Natural Selection Shapes Variation in Genome-wide Recombination Rate in Drosophila pseudoobscura
Current Biology, 2019 While recombination is widely recognized to be a key modulator of numerous evolutionary phenomena, we have a poor understanding of how recombination rate itself varies and evolves within a species.

Proceedings of the Royal Society B, 2019 Selfish ‘meiotic drive’ alleles are transmitted to more than 50% of offspring, allowing them to rapidly invade populations even if they reduce the fitness of individuals carrying them.

Visualizing septins in early Drosophila embryos [PDF]
Methods in Cell Biology, Elsevier, 2016, Septins, 136, pp.183, 2016 Functional studies in Drosophila have been key for establishing a role for the septin family of proteins in animal cell division and thus extending for the first time observations from the budding yeast to animal cells. Visualizing the distribution of specific septins in different Drosophila tissues and, in particular, in the Drosophila embryo ...

Molecular Ecology, 2018 The gene arrangements of Drosophila have played a prominent role in the history of evolutionary biology from the original quantification of genetic diversity to current studies of the mechanisms for the origin and establishment of new inversion mutations

Genetics, 2016 Chromosomal rearrangements can shape the structure of genetic variation in the genome directly through alteration of genes at breakpoints or indirectly by holding combinations of genetic variants together due to reduced recombination.

Extensive exchange of transposable elements in the Drosophila pseudoobscura group
Mobile DNA, 2018 As species diverge, so does their transposable element (TE) content. Within a genome, TE families may eventually become dormant due to host-silencing mechanisms, natural selection and the accumulation of inactive copies. The transmission of active copies
