Meiotic drive does not impede success in sperm competition in the stalk-eyed fly, Teleopsis dalmanniS. Bates, L. Meade and A. Pomiankowski, Evolution, 2023.
Male X-linked meiotic drive systems, which cause the degeneration of Y-bearing sperm, are common in the Diptera. Sperm killing is typically associated with fitness costs that arise from the destruction of wildtype sperm and collateral damage to maturing drive sperm, resulting in ... |

X chromosome drive is constrained by sexual selection and influences ornament evolutionK. A. Paczolt, G. T. Welsh and G. S. Wilkinson, Proceedings of the Royal Society B: Biological Sciences, 290:20230929. 2023.
Experimental evolution provides an integrative method for revealing complex interactions among evolutionary processes. One such interaction involves sex-linked selfish genetic elements and sexual selection. X-linked segregation distorters, a type of selfish genetic element, ... |

Impacts of sex ratio meiotic drive on genome structure and function in a stalk-eyed flyJ. A. Reinhardt, R. H. Baker, A. V. Zimin, C. Ladias, K. A. Paczolt, J. H. Werren, C. Y. Hayashi and G. S. Wilkinson, Genome Biology Evolution, 2023.
Stalk-eyed flies in the genus Teleopsis carry selfish genetic elements that induce sex ratio meiotic drive (SR) and impact the fitness of male and female carriers. Here, we assemble and describe a chromosome-level genome assembly of the stalk-eyed fly, Teleopsis dalmanni, to ... |

Meiotic drive does not impede success in sperm competition in the stalk-eyed fly, Teleopsis dalmanniS. Bates, L. Meade and A. Pomiankowski, bioRxiv, 2022.
Meiotic drive genes are selfish genetic elements that distort Mendelian patterns of inheritance to bias transmission in their favour. We use the stalk-eyed fly, Teleopsis dalmanni, to investigate the fitness effects associated with a meiotic drive gene called Sex Ratio (SR), ... |

Meiotic drive does not cause condition-dependent reduction of the sexual ornament in stalk-eyed fliesS. R. Finnegan, M. Mondani, K. Fowler and A. Pomiankowski, Journal of Evolutionary Biology, 11. 2021.
Meiotic drive systems are associated with low-frequency chromosomal inversions. These are expected to accumulate deleterious mutations due to reduced recombination and low effective population size. We test this prediction using the 'sex-ratio' (SR) meiotic drive system of the ... |
