This study shows that facultative sex in wasps leads to reduced fecundity and selection against mixed sexual-asexual genotypes, suggesting costs that limit the persistence of facultative sex.

The paper examines sex-biased gene expression in a sexual and parthenogenetic stick insect, finding early gonadal expression patterns suggesting unresolved sexual antagonism.

The paper investigates whether dosage compensation and meiotic sex chromosome inactivation persist in parthenogenetic stick insects with relaxed selection, finding both mechanisms are conserved despite the absence of male selection.

This study examines dosage compensation and meiotic sex chromosome inactivation in stick insects, finding that X chromosome expression is dynamically regulated in male tissues during development.

The paper analyzes centromere structure and function in stick insects, revealing a functionally monocentric system with holocentric-like features and chromosome-specific centromeres.

The paper generates a high-quality genome assembly for the dyeing poison frog and shows transposable elements drive genome size evolution and complicate genotyping.

The paper examines genomic divergence in Drosophila montana to identify cold adaptation signatures, finding 250 genes with accelerated divergence and outlier loci on the X chromosome.
