A selfish genetic element linked to increased lifespan impacts metabolism in female house miceLopes, P. C. and A. K. Lindholm, The Journal of Experimental Biology, 2019:212704. 2019.
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 ... |

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 ... |

Sustainability as a framework for considering gene drive mice for invasive rodent eradicationBarnhill-Dilling, SKS, M.; Blondel, D. V.; Godwin, J., Sustainability, 11:1334. 2019.
Gene drives represent a dynamic and controversial set of technologies with applications that range from mosquito control to the conservation of biological diversity on islands. Currently, gene drives are being developed in mice that may one day serve as an important tool for ... |

Carrying a selfish genetic element predicts increased migration propensity in free-living wild house miceRunge, J-NL, Anna K., Proceedings of the Royal Society B: Biological Sciences, 285:20181333. 2018.
Life is built on cooperation between genes, which makes it vulnerable to parasitism. Selfish genetic elements that exploit this cooperation can achieve large fitness gains by increasing their transmission relative to the rest of the genome. This leads to counter-adaptations that ... |

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 ... |

No evidence for female discrimination against male house mice carrying a selfish genetic elementSutter, AL, A. K., Current Zoology, 62:675-685. 2016.
Meiotic drivers distort transmission to the next generation in their favor, with detrimental effects on the fitness of their homologues and the rest of the genome. Male carriers of meiotic drivers commonly inflict costs on their mates through genetic incompatibility, reduced ... |
|
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 ... |

Female house mice avoid fertilization by t haplotype incompatible males in a mate choice experimentManser, AK, B.; Lindholm, A. K., Journal of Evolutionary Biology, 28:54-64. 2015.
The t haplotype in house mice is a well-known selfish genetic element with detrimental, nonadditive fitness consequences to its carriers: recessive lethal mutations cause t/t homozygotes to perish in utero. Given the severe genetic incompatibility imposed by the t haplotype, we ... |

Detrimental effects of an autosomal selfish genetic element on sperm competitiveness in house miceSutter, AL, A. K., Proceedings of the Royal Society B-Biological Sciences, 282:1-8. 2015.
Female multiple mating (polyandry) is widespread across many animal taxa and indirect genetic benefits are a major evolutionary force favouring polyandry. An incentive for polyandry arises when multiple mating leads to sperm competition that disadvantages sperm from genetically ... |

Meiotic drive influences the outcome of sexually antagonistic selection at a linked locusPatten, MM, Journal of Evolutionary Biology, 27:2360-2370. 2014.
Most meiotic drivers, such as the t-haplotype in Mus and the segregation distorter (SD) in Drosophila, act in a sex-specific manner, gaining a transmission advantage through one sex although suffering only the fitness costs associated with the driver in the other. Their ... |

Transmission ratio distortion in miceLyon, MF, Annual Review of Genetics, 37:393-408. 2003.
The most studied example of transmission ratio distortion (TRD) in mice is that of the t-complex. This is a variant-region of Chromosome 17 which exists as a polymorphism in wild mice. Males heterozygous for a t-haplotype and a normal Chr 17 transmit-the t haplotype to >50% of ... |

Nonrandom segregation during meiosis: the unfairness of femalesde Villena, FPMS, C., Mammalian Genome, 12:331-339. 2001.
Most geneticists assume that chromosome segregation during meiosis is Mendelian (i.e., each allele at each locus is represented equally in the gametes). The great majority of reports that discuss non-Mendelian transmission have focused on systems of gametic selection, such as the ... |

Segregation distortion of mouse t-haplotypes: The molecular basis emergesSchimenti, J, Trends in Genetics, 16:240-243. 2000.
The t haplotype is an ancestral version of proximal mouse chromosome 17 that has evolved mechanisms to persist as an intact genomic variant in mouse populations. t haplotypes contain mutations that affect embryonic development, male fertility and male transmission ratio ... |

Segregation distortion in a deme structured population: opposing demands of gene, individual and group selectionvan Boven, MW, F. J., Journal of Evolutionary Biology, 12:80-93. 1999.
The evolution of segregation distortion is governed by the interplay of selection at different levels. Despite their systematic advantage at the gamete level, none of the well-known segregation distorters spreads to fixation since they induce severe negative fitness effects at ... |
|
Evolution of segregation distortion: Potential for a high degree of polymorphismvan Boven, MW, F. J., Journal of Theoretical Biology, 192:131-142. 1998.
By means of a population genetical model, we study the evolution of segregation distortion. Most models of segregation distortion focus on a single distorter allele. In contrast, we consider the competition between a large number of distorters. Motivated by systems as the t ... |

Putting the brake on drive: meiotic drive of t haplotypes in natural populations of miceArdlie, KG, Trends in Genetics, 14:189-193. 1998.
Mouse t haplotypes are a 'selfish' form of chromosome 17 that show non-mendelian transmission from heterozygous +/t males. The considerable transmission bias in favour of t haplotypes should result in very high frequencies of these chromosomes in natural populations, but they ... |

Segregation distortersLyttle, TW, Annual Review of Genetics, 25:511-557. 1991.
Segregation distorters are genetic elements that exhibit the phenomenon of meiotic drive; that is, the mechanics of the meiotic divisions cause one member of a pair of heterozygous alleles or heteromorphic chromosomes to be transmitted to progeny in excess of the expected ... |

The Genetic Basis of Transmission-Ratio Distortion and Male Sterility Due to the t ComplexLyon, MF, American Naturalist, 137:349-358. 1991.
The abnormal transmission ratios observed in male mice heterozygous for a complete t haplotype have been shown by breeding studies to be due to three or more distorter genes acting on a responder gene. The action of the t form of the responder is relatively resistant to this ... |

Behavioral reduction in the transmission of deleterious t-haplotypes by wild house miceLenington, SH, I. L., The American Naturalist, 137:366-378. 1991.
About 25% of wild house mice are heterozygous (+/t) for a variable recessive haplotype of the T locus. Although t haplotypes are highly deleterious when homozygous, they are maintained in wild mouse populations because they are associated with transmission-ratio distortion in ... |
