Answer 1

Heterochromatin is the darkly stained area, they are darkly stained because they are closely packed. The lightly stained area is called euchromatin and are loosely packed.

Answer 2

Chromatin inside a cell can be compacted to varying degrees depending on a cell's stage in the cell cycle.

Inside the nucleus, chromatin exists as euchromatin or heterochromatin.

During interphase of the cycle, the cell does not divide but it undergoes a period of growth.

Less compact chromatin is form is known as euchromatin.

A small percentage of chromatin exists as heterochromatin. This chromatin is tightly packed, not allowing gene transcription to take place.

Heterochromatin stains more darkly with dyes than does euchromatin.

So, the darkly stained regions of chromatin during interphase is known as Heterochromatin.
