Epigenetic conflict on a degenerating Y chromosome increases mutational burden in Drosophila males

Selfish DNA such as transposable elements cause intragenomic conflict. This study finds that on an evolutionarily young, gene-rich Drosophila Y chromosome, transposable elements evade heterochromatic suppression, leading to elevated transposition rates in males.
