An introgressed gene causes meiotic drive in Neurospora sitophilaJ. Svedberg, A. A. Vogan, N. A. Rhoades, D. Sarmarajeewa, D. J. Jacobson, M. Lascoux, T. M. Hammond and H. Johannesson, Proceedings of the National Academy of Sciences of the United States of America, 118:9. 2021.
Meiotic drive elements cause their own preferential transmission following meiosis. In fungi, this phenomenon takes the shape of spore killing, and in the filamentous ascomycete Neurospora sitophila, the Sk-1 spore killer element is found in many natural populations. In this ... |

Autosomal suppression and fitness costs of an old driving X chromosome in Drosophila testaceaG. 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 ... |

Combinations of Spok genes create multiple meiotic drivers in PodosporaA. A. Vogan, S. L. Ament-Velásquez, A. Granger-Farbos, J. Svedberg, E. Bastiaans, A. J. M. Debets, V. Coustou, H. Yvanne, C. Clavé, S. J. Saupe and H. Johannesson, eLife, 8:e46454. 2019.
Meiotic drive is the preferential transmission of a particular allele during sexual reproduction. The phenomenon is observed as spore killing in multiple fungi. In natural populations of Podospora anserina, seven spore killer types (Psks) have been identified through classical ... |

A family of killersM. De Carvalho and S. E. Zanders, eLife, 8:e49211. 2019.
Spok genes are meiotic drivers that increase their own chances of transmission by killing gametes that do not inherit them. |
