Historically, the term "intercalary heterochromatin" was based on the finding that induced chromosome rearrangements occur at a higher frequency in the corresponding regions. The available molecular genetic data and, in particular, the results of the Drosophila Genome Project made it possible to decide between two possible explanations of the preferential location of chromosome rearrangement breakpoints in intercalary heterochromatin regions. Namely, a higher frequency of radiation-induced rearrangements in these regions correlates with the DNA content and probably lacks an association with the features of chromatin organization.
