The western mosquitofish (Gambusia affinis) is a sexually dimorphic poeciliid fish known for its worldwide biological invasion and therefore an important research model for studying invasion biology. This organism may also be used as a suitable model to explore sex chromosome evolution and reproductive development in terms of differentiation of ZW sex chromosomes, ovoviviparity, and specialization of reproductive organs. However, there is a lack of high-quality genomic data for the female G. affinis; hence, this study aimed to generate a chromosome-level genome assembly for it.

雌性西方蚊鱼（Gambusia affinis）的染色体水平基因组组装。


西方食蚊鱼（ Gambusia affinis ）是一种两性异形的鳀科鱼类，以其全球性的生物入侵而闻名，因此是研究入侵生物学的重要研究模型。该生物体还可以用作探索性染色体进化和生殖发育的合适模型，包括ZW性染色体的分化、卵胎生和生殖器官的特化。然而，雌性G. affinis缺乏高质量的基因组数据；因此，这项研究旨在为其生成染色体水平的基因组组装。
