Quizplus · Accepted Answer

Constitutive heterochromatin is a permanent form of genetic material that remains highly condensed in all cells and has low gene density. Euchromatin is the opposite, with low condensation and high gene density. Facultative heterochromatin refers to regions of the chromosome that can switch between euchromatic and heterochromatic states. A Barr body is a condensed and inactivated X chromosome in female mammalian cells.
