The assembly of chromatin into heterochromatin at the telomere. The assembly of chromatin into heterochromatin near the centromere. The assembly of chromatin into heterochromatin, a compact and highly condensed form that is often, but not always, transcriptionally silent. Any process that results in the specification, formation or maintenance of the physical structure of eukaryotic heterochromatin, a compact and highly condensed form of chromatin. Any process that results in the specification, formation or maintenance of the physical structure of eukaryotic chromatin. Any process that results in the assembly of chromatin into heterochromatin and contributes to chromatin silencing. Any process by which DNA and associated proteins are formed into a compact, orderly structure. The formation or destruction of chromatin structures. The assembly of DNA, histone proteins, and other associated proteins into chromatin structure, beginning with the formation of the basic unit, the nucleosome, followed by organization of the nucleosomes into higher order structures, ultimately giving rise to a complex organization of specific domains within the nucleus. The aggregation, arrangement and bonding together of a cellular component. Compensating for the two-fold variation in X-chromosome:autosome ratios between sexes by a global inactivation of all, or most of, the genes on one of the X-chromosomes in the XX sex by the mechanism of heterochromatin formation. Any process that modulates the frequency, rate, extent or location of heterochromatin formation. Dynamic structural changes to eukaryotic chromatin occurring throughout the cell division cycle. These changes range from the local changes necessary for transcriptional regulation to global changes necessary for chromosome segregation. Any process that activates or increases the frequency, rate or extent of heterochromatin formation. Any process that stops, prevents or reduces the frequency, rate or extent of heterochromatin formation. The alteration of DNA or protein in chromatin, which may result in changing the chromatin structure.
