Red queen’s race: rapid evolutionary dynamics of an expanding family of meiotic drive factors and their hpRNA suppressors

J. Vedanayagam, C.-J. Lin and E. C. Lai,  bioRxiv,  2021.08.05.454923. 2021.
Meiotic drivers are a class of selfish genetic elements that are widespread across eukaryotes. Their activities are often detrimental to organismal fitness and thus trigger drive suppression to ensure fair segregation during meiosis. Accordingly, their existence is frequently ...

Selfish genetic elements and male fertility

R. L. Verspoor, T. A. R. Price and N. Wedell,  Philosophical Transactions of the Royal Society B-Biological Sciences,  375:7. 2020.
Selfish genetic elements (SGEs) are diverse and near ubiquitous in Eukaryotes and can be potent drivers of evolution. Here, we discuss SGEs that specifically act on sperm to gain a transmission advantage to the next generation. The diverse SGEs that affect sperm often impose ...

Autosomal suppression and fitness costs of an old driving X chromosome in Drosophila testacea

G. Keais, S. Lu and S. Perlman,  Journal of Evolutionary Biology,  2020.
Driving X chromosomes (XDs) are meiotic drivers that bias their own transmission through males by killing Y-bearing gametes. These chromosomes can in theory spread rapidly in populations and cause extinction, but many are found as balanced polymorphisms or as ?cryptic? XDs shut ...
