New perspectives on the causes and consequences of male meiotic drive
Gametogenesis is vulnerable to selfish genetic elements that bias their transmission to the
next generation by cheating meiosis. These so-called meiotic drivers are widespread in …

The hpRNA/RNAi pathway is essential to resolve intragenomic conflict in the Drosophila male germline
Intragenomic conflicts are fueled by rapidly evolving selfish genetic elements, which induce
selective pressures to innovate opposing repressive mechanisms. This is patently manifest …
