摘要

具有减数分裂驱动力的染色体区域比与其竞争的同源染色体区域表现出偏向传递（50%）。这些区域通常有两个突出的遗传特征：减数分裂交叉抑制和快速进化的多拷贝基因家族。异形性染色体（如 XY）与表现出减数分裂驱动力的染色体区域通常具有这两个遗传特征。在此，我们将讨论减数分裂驱动与性染色体进化之间的相似之处、减数分裂驱动如何影响异形性染色体的分化、研究性染色体减数分裂驱动的实验方法，以及具有高质量基因组组装的传统和非传统模式生物的减数分裂驱动。新近获得的高质量性染色体序列的多样性使我们能够通过减数分裂驱动的视角重新审视性染色体进化的传统模型。

Out with the old, in with the new: Meiotic driving of sex chromosome evolution

Chromosomal regions with meiotic drivers exhibit biased transmission (> 50 %) over their competing homologous chromosomal region. These regions often have two prominent genetic features: suppressed meiotic crossing over and rapidly evolving multicopy gene families. Heteromorphic sex chromosomes (e.g., XY) often share these two genetic features with chromosomal regions exhibiting meiotic drive. Here, we discuss parallels between meiotic drive and sex chromosome evolution, how the divergence of heteromorphic sex chromosomes can be influenced by meiotic drive, experimental approaches to study meiotic drive on sex chromosomes, and meiotic drive in traditional and non-traditional model organisms with high-quality genome assemblies. The newly available diversity of high-quality sex chromosome sequences allows us to revisit conventional models of sex chromosome evolution through the lens of meiotic drive.

期刊介绍： Seminars in Cell and Developmental Biology is a review journal dedicated to keeping scientists informed of developments in the field of molecular cell and developmental biology, on a topic by topic basis. Each issue is thematic in approach, devoted to an important topic of interest to cell and developmental biologists, focusing on the latest advances and their specific implications. The aim of each issue is to provide a coordinated, readable, and lively review of a selected area, published rapidly to ensure currency.
