摘要
在有两性之分的动植物中，最普遍的染色体性别决定系统是雄性异配的 XY 系统和雌性异配的 ZW 系统。有了全相位、染色体尺度的基因组组装，找出哪个物种具有哪个系统就变得容易多了。现在，一项新的研究为 Amborella trichopoda 提供了这样一个基因组，其 Z 和 W 性染色体几乎完全组装完毕。
The most widespread chromosomal sex determination systems in plants and animals with separate sexes are the XY system, in which males are heterogametic, and the ZW system, in which females are heterogametic. Figuring out which species has which system has become easier with fully phased, chromosome-scale genome assemblies. A new study now provides such a genome for Amborella trichopoda, with its Z and W sex chromosomes nearly completely assembled.
