constitutive heterochromatin formation +   
The compaction of chromatin into heterochromatin, a conformation that is refractory to transcription. Constitutive heterochromatin cannot be converted back to euchromatin, the transcriptionally-active conformation. In metazoa, this involves the methylation of histone H3K9.
dosage compensation by inactivation of X chromosome +   
facultative heterochromatin formation +   
heterochromatin boundary formation  
negative regulation of heterochromatin formation +
