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 ... |

Mitonuclear interactions, mtDNA-mediated thermal plasticity, and implications for the Trojan Female Technique for pest controlJ. N. Wolff, D. M. Tompkins, N. J. Gemmell and D. K. Dowling, Scientific Reports, 6. 2016.
Here we test whether the male-sterilizing effects previously associated with the mt: Cyt-b mutation are consistent across three thermal and three nuclear genomic contexts. The effects of this mutation were indeed moderated by the nuclear background and thermal environment, but ... |

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 ... |
