Meiotic drivers violate Mendelian principles by biasing their segregation to the next generation, often at a cost to the individual. This cost leads to a cyclical arms race between drivers and host genomes where drivers acquire modifications to cheat, and the rest of the genome evolves counter-drive mechanisms to restore fair segregation. Repeated bouts of innovation on both sides of the conflict can have consequences for genome and species evolution. Much of the foundational and recent work in this field has found its home in the Genetics Society of America journals. In this commentary, Edvalson and Larracuente highlight some recent work published in these journals that address key questions about the evolutionary consequences of meiotic drive.
减数分裂驱动因子通过偏向其向下一代的分离而违反孟德尔定律,这通常会给个体带来代价。这种代价导致驱动因子与宿主基因组之间的周期性军备竞赛,其中驱动因子获得欺骗性的修饰,而基因组的其余部分则进化出反驱动机制以恢复公平分离。冲突双方反复的创新回合可能会对基因组和物种进化产生影响。该领域的许多基础研究和近期工作都发表在美国遗传学会的期刊上。在这篇评论中,埃德瓦尔森和拉腊昆特强调了这些期刊上发表的一些近期研究,这些研究解决了关于减数分裂驱动的进化后果的关键问题。
