Rapid evolutionary dynamics of an expanding family of Drosophila meiotic drive factors and their hpRNA suppressors

The Dox meiotic drive system distorts the sex-ratio in Drosophila simulans. Here, the authors reconstruct the step-wise emergence, and recent amplification of Dox superfamily genes in parallel with the emergence of autosomal hairpin RNA-class siRNA loci that target subsets of these putative drivers Overall design: The study reports small RNA and RNA-seq data from testis from 3 closely related species in the Drosophila simulans clade.
