Heya here is the ans of your qun ...

☆The major difference between heterochromatin and euchromatin ...

☆ 1. Euchromatin - Euchromatin is deeply stained in divisional cycle but less stained in interphase.

2. Euchromatic regions are seen to their DNA earlier than heterochromatin. They replicate during ‘S’ phase.

3.The chromatin fibres in this region are loosely coiled as compared with hetero­ chromatic regions..

☆ 1. Heterochromatin - The chromatin fibres in this region are more tightly folded than euchromatic regions.

2. Heterochromatin is more affected than euchro­matin by temperature, sex, age of parents, proximity to the centromere.

3. Heterochromatic regions are seen to replicate during the onset of divisional cycle.....
