Chromosome-level genome assembly of the female western mosquitofish (Gambusia affinis)

摘要

The western mosquitofish ( ) 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 ; hence, this study aimed to generate a chromosome-level genome assembly for it.
