The effect of mating complexity on gene drive dynamicsP. Verma, R. G. Reeves, S. Simon, M. Otto and C. S. Gokhale, bioRxiv, 2021.09.16.460618. 2021.
Gene drive technology is being presented as a means to deliver on some of the global challenges humanity faces today in healthcare, agriculture and conservation. However, there is a limited understanding of the consequences of releasing self-perpetuating transgenic organisms into ... |

Sterile males and females can synergistically suppress wild pests targeted by sterile insect techniqueY. Ikegawa, K. Ito, C. Himuro and A. Honma, Journal of Theoretical Biology, 530. 2021.
We constructed a mathematical model to examine the contribution of sterile males and females to the pest-control effect and the synergy between them. We consider that males seek out and court females in accord with their own female searching ability and preference, and that ... |

Mosquito Sexual Selection and Reproductive Control ProgramsL. J. Cator, C. A. S. Wyer and L. C. Harrington, Trends in Parasitology, 2021.
Recent work has generated many key insights about specific aspects of mating behavior and physiology. Here, we synthesize these findings and classify swarming mosquito systems as polygynous. Male mating success is highly variable in swarms and evidence suggests that it is likely ... |

Selfish genes and sexual selection: the impact of genomic parasites on host reproductionN. Wedell, Journal of Zoology, 311:1-12. 2020.Selfish genetic elements (SGEs) such as replicating mobile elements, segregation distorters and maternally inherited endosymbionts, bias their transmission success relative to the rest of the genome to increase in representation in subsequent generations. As such, they generate ... |

A selfish genetic element linked to increased lifespan impacts metabolism in female house miceP. C. Lopes and A. K. Lindholm, Journal of Experimental Biology, 22:4. 2020.
Gene drive systems can lead to the evolution of traits that further enhance the transmission of the driving element. In gene drive, one allele is transmitted to offspring at a higher frequency than the homologous allele. This has a range of consequences, which generally include a ... |

Effects of a male meiotic driver on male and female transcriptomes in the house mouseA. Lindholm, A. Sutter, S. Kunzel, D. Tautz and H. Rehrauer, Proceedings of the Royal Society B-Biological Sciences, 286:1-8. 2019.
Not all genetic loci follow Mendel's rules, and the evolutionary consequences of this are not yet fully known. Genomic conflict involving multiple loci is a likely outcome, as restoration of Mendelian inheritance patterns will be selected for, and sexual conflict may also arise ... |

Does meiotic drive alter male mate preference?S. R. Finnegan, L. Nitsche, M. Mondani, M. F. Camus, K. Fowler and A. Pomiankowski, Behavioral Ecology, 13:194-201. 2019.
Male mate preferences have been demonstrated across a range of species, including the Malaysian stalk-eyed fly, Teleopsis dalmanni. This species is subject to sex-ratio (SR), an X-linked male meiotic driver, which causes the dysfunction of Y-sperm and the production of all-female ... |

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 ... |
