Heterochromatin is primarily classified into two types: constitutive and facultative heterochromatin. Constitutive heterochromatin is always in a compact form and is typically found in regions such as centromeres and telomeres, playing a crucial role in maintaining chromosome stability. In contrast, facultative heterochromatin can switch between a condensed and relaxed state and is involved in gene regulation, allowing for the silencing of specific genes based on developmental or environmental cues.
