Polyandry blocks gene drive in a wild house mouse populationA. Manser, B. Konig and A. K. Lindholm, Nature Communications, 11:8. 2020.
Here, we study the impact of polyandry on a well-known gene drive, called t haplotype, in an intensively monitored population of wild house mice. First, we show that house mice are highly polyandrous: 47% of 682 litters were sired by more than one male. Second, we find that ... |

Selfish genetic elements and male fertilityR. 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 ... |

An X-linked meiotic drive allele has strong, recessive fitness costs in female Drosophila pseudoobscuraW. Larner, T. Price, L. Holman and N. Wedell, Proceedings of the Royal Society B-Biological Sciences, 286:9. 2019.
Selfish 'meiotic drive' alleles are transmitted to more than 50% of offspring, allowing them to rapidly invade populations even if they reduce the fitness of individuals carrying them. Theory predicts that drivers should either fix or go extinct, yet some drivers defy these ... |

Controlling invasive rodents via synthetic gene drive and the role of polyandryManser, AC, S. J.; Sutter, A.; Blondel, D. V.; Serr, M.; Godwin, J.; Price, T. A. R., Proceedings of the Royal Society B-Biological Sciences, 286:9. 2019.
House mice are a major ecosystem pest, particularly threatening island ecosystems as a non-native invasive species. Rapid advances in synthetic biology offer new avenues to control pest species for biodiversity conservation. Recently, a synthetic sperm-killing gene drive ... |

Sperm competition suppresses gene drive among experimentally evolving populations of house miceManser, AL, A. K.; Simmons, L. W.; Firman, R. C., Molecular Ecology, 26:5784-5792. 2017.
Drive genes are genetic elements that manipulate the 50% ratio of Mendelian inheritance in their own favour, allowing them to rapidly propagate through populations. The action of drive genes is often hidden, making detection and identification inherently difficult. Yet drive ... |

Meiotic drive changes sperm precedence patterns in house mice: potential for male alternative mating tactics?Sutter, AL, A. K., BMC Evolutionary Biology, 16:15. 2016.
Background: With female multiple mating (polyandry), male-male competition extends to after copulation (sperm competition). Males respond to this selective pressure through physiological, morphological and behavioural adaptations. Sperm competitiveness is commonly decreased in ... |

Sperm traits of masculinized fish relative to wild-type males: a systematic review and meta-analysesA. M. Senior, S. L. Johnson and S. Nakagawa, Fish and Fisheries, 17:143-164. 2014.
Environmental sex reversal (ESR), whereby environmental effects (e.g. exogenous chemicals) override genetic sex determination, is a commonly used technique in aquaculture and physiology research. We performed a systematic review and meta-analyses of the literature that compares ... |
