The epigenome of evolving Drosophila neo-sex chromosomes: dosage compensation and heterochromatin formation.

Sex chromosomes originated from autosomes but have evolved a highly specialized chromatin structure. Drosophila Y chromosomes are composed entirely of silent heterochromatin, while male X chromosomes have highly accessible chromatin and are hypertranscribed as a result of dosage compensation. Here,...
