heterochromatization
heterochromatization Cytol. (ˌhɛtərəʊˌkrəʊmətaɪˈzeɪʃən) Also ˌheteroˌchromatiniˈzation. [f. prec. + -ization.] A change of state of chromosome material in which it becomes heterochromatic and the action of the genes is modified or suppressed; also, the extent to which such a change has occurred.

Position-effect variegation
Also, the austerity of the variegated phenotype can be altered by the distance of the heterochromatic region from the breakpoint. The silencing of euchromatic genes occurs when the genes get placed into a new heterochromatic neighborhood.

What sequences are between adjacent genes? The human genome has a lot of non-coding regions, which include regulatory elements, repetitive DNA, and introns. Suppose there are two adjacent genes on a chromosome, and th...
Repeat regions need not be heterochromatinized and conversely not all heterochromatic regions consist of repeats.

In G-bands, the dark regions tend to be heterochromatic, late-replicating and AT rich.

RNA-induced transcriptional silencing
The RITS complex localizes to heterochromatic regions through the base pairing of the nascent heterochromatic transcripts as well as through the Chp chromodomain In higher eukaryotes, RNAi-dependent heterochromatic silencing appears to play a larger role in germline cells than in primary cells or cell lines, and

G banding
Heterochromatic regions, which tend to be rich with adenine and thymine (AT-rich) DNA and relatively gene-poor, stain more darkly in G-banding.

Abby Dernburg
Heterochromatic regions of chromosomes tend to associate together in a specific compartment of the nucleus. Dernburg found that when a region of heterochromatin was inserted near the brown gene, the gene would associate with a heterochromatic region of the nucleus
