Heterochromatin - an overview | ScienceDirect Topics
Heterochromatin is a cytologically dense material that is typically found at centromeres and telomeres . It mostly consists of repetitive DNA sequences and is relatively gene poor. Its most notable property is its ability to silence euchromatic gene expression. www.sciencedirect.com

Here's a good summary of knobs, which says that they are " _typically telomeric_ ," " _tandemly repeated DNA sequences [that] appear as distinct, heteropycnotic regions located at certain sites on specific chromosomes and look much like beads on a string_ " and are involved in: > increased recombina...

Constitutive heterochromatin
The regions that stain darker are regions of constitutive heterochromatin. Constitutive heterochromatin is not to be confused with facultative heterochromatin, which is less condensed, less stable, and much less polymorphic, and wikipedia.org
