PLoS Genetics, 2009 In nature, closely related species may hybridize while still retaining their distinctive identities. Chromosomal regions that experience reduced recombination in hybrids, such as within inversions, have been hypothesized to contribute to the maintenance ...

Mistaken Identity: Another Bias in the Use of Relative Genetic Divergence Measures for Detecting Interspecies Introgression. [PDF]
PLoS ONE, 2016 Measures of genetic divergence have long been used to identify evolutionary processes operating within and between species. However, recent reviews have described a bias in the use of relative divergence measures towards incorrectly identifying genomic ...

Sex-specific embryonic gene expression in species with newly evolved sex chromosomes. [PDF]
PLoS Genetics, 2014 Sex chromosome dosage differences between females and males are a significant form of natural genetic variation in many species. Like many species with chromosomal sex determination, Drosophila females have two X chromosomes, while males have one X and ...

Identification of male- and female-specific olfaction genes in antennae of the oriental fruit fly (Bactrocera dorsalis) [PDF]
, 2016 The oriental fruit fly (Bactrocera dorsalis) is a species of tephritid fruit fly, endemic to Southeast Asia but also introduced to many regions of the US, and it is one of the major pest species with a broad host range of cultivated and wild fruits ...

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

Massive gene amplification on a recently formed Drosophila Y chromosome. [PDF]
, 2019 Widespread loss of genes on the Y is considered a hallmark of sex chromosome differentiation. Here we show that the initial stages of Y evolution are driven by massive amplification of distinct classes of genes. The neo-Y chromosome of Drosophila miranda

Mitochondrial gene divergence of Colombian Drosophila pseudoobscura [PDF]
Molecular Biology and Evolution, 1996 Isolated populations of drosophila pseudoobscura, separated from North American populations by about 2,400 km, were found in Colombia in 1960. We compared for sequences of the small ribosomal RNA (srRNA) gene on the mitochondria between North American and Colombian D. pseudoobscura in order to clarify the age of the Colombian isolates.

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.

Temporalchanges in relative frequencies of third chromosome inversions of Drosophila pseudoobscura in Mexican populations [PDF]
, 2008 Variations in relative frequencies of third chromosome inversions during 1974-2000 in three populations of D. pseudoobscura from Mexico were analyzed. The general constitution of these populations is formed from ten up to 15 different inversions, been ...
