Suppose a region of a chromosome is gene dense and stains lightly.What is it?

Question

Euchromatin is a less condensed region of chromatin that is gene-dense and typically stains lightly. This is in contrast to heterochromatin, which is gene-poor and stains darker, and Barr bodies, which are condensed, inactive X chromosomes seen in females. CpG islands are also gene-rich regions, but they are typically unmethylated and do not necessarily affect staining. Xist, on the other hand, is a gene that is involved in X chromosome inactivation and does not directly relate to staining patterns.
