Dosage compensation and meiotic sex chromosome inactivation are maintained in the absence of selection

2025-07-31

Abstract excerpt

Dosage compensation and meiotic sex chromosome inactivation (MSCI) are key mechanisms regulating gene expression from the X chromosome in male-heterogametic species. While the convergent evolution of these mechanisms is well-documented, their evolutionary fate under relaxed selection remains poorly understood. Here, we test whether dosage compensation and MSCI persist following three independent transitions to par...
