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.

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

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.

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.

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

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.

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.

Genomic changes following the reversal of a Y chromosome to an autosome in Drosophila pseudoobscura
Evolution; international journal of organic evolution, 2017 Robertsonian translocations resulting in fusions between sex chromosomes and autosomes shape karyotype evolution by creating new sex chromosomes from autosomes.

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

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.
