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 ... |

Selfing is the safest sex for Caenorhabditis tropicalisL. M. Noble, J. Yuen, L. Stevens, N. D. Moya, R. Persaud, M. Moscatelli, J. L. Jackson, G. Zhang, R. Chitrakar, L. R. Baugh, C. Braendle, E. C. Andersen, H. S. Seidel and M. V. Rockman, eLife, 10:e62587. 2021.
We generated a chromosomal-scale genome for C. tropicalis and surveyed global diversity. Population structure is very strong, and islands of extreme divergence punctuate a genomic background that is highly homogeneous around the globe. Outbreeding depression in the laboratory is ... |

Mosquito Sexual Selection and Reproductive Control ProgramsL. J. Cator, C. A. S. Wyer and L. C. Harrington, Trends in Parasitology, 37:330-339. 2021.
The field of mosquito mating biology has experienced a considerable expansion in the past decade. 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 ... |

Pest demography critically determines the viability of synthetic gene drives for population controlK. E. Wilkins, T. A. A. Prowse, P. Cassey, P. Q. Thomas and J. V. Ross, Mathematical Biosciences, 305:160-169. 2018.
Synthetic gene drives offer a novel solution for the control of invasive alien species. CRISPR-based gene drives can positively bias their own inheritance, and comprise a DNA sequence that is replicated by homologous recombination. Since gene drives can be positioned to silence ... |

Selfish DNA and breeding system in flowering plantsBurt, AT, R., Proceedings of the Royal Society B-Biological Sciences, 265:141-146. 1998.
In many species, some individuals carry one or more B chromosomes: extra, or supernumerary chromosomes not part of the normal complement. In most well-studied cases, B's lower the fitness of their carrier and persist in populations only because of accumulation mechanisms ... |
