. The major difference between heterochromatin and euchromatin is that heterochromatin is such part of the chromosomes which is a firmly packed form and are genetically inactive while euchromatin is an uncoiled loosely packed form of chromatin and are genetically active.

Euchromatin is defined as the area of the chromosome which is rich in gene concentration and actively participates in the transcription process. An enhancer region is a stretch of DNA that alters gene. Euchromatin has a less compact structure whereas heterochromatin is more compact and composed of an array of nucleosomes condensed into a fiber.
