AbstractSex chromosomes often evolve unique patterns of gene expression in spermatogenesis. In many species, sex-linked genes are downregulated during meiosis in response to asynapsis of the heterogametic sex chromosome pair (meiotic sex chromosome inactivation; MSCI). Our understanding of this process has been limited to a handful of species, including mammals, Drosophila, and C. elegans. Based on findings from these taxa, MSCI has been viewed as likely a conserved process.
