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