Genetics of Speciation

The most recent issue of the Journal of Heredity contains a bunch of articles from a symposium on the “Genetics of Speciation” organized by Loren Rieseberg. Included in the collection is an article by Allen Orr and two of his students on speciation in Drosophila, which discusses mapping speciation genes, the role of meiotic drive in speciation, and Dobzhansky Muller incompatibilities via gene translocation (the latter two are the topics of recent papers from Orr’s group — here and here). Also in the special issue is an article from Mohamed Noor’s lab on mapping inversion breakpoints between two sibling species of Drosophila, an article on expression of duplicate genes in polyploid and hybrid plants, and a few others.
