In telophase stage chromosomes decondense and lose their individuality.

Answer

### Step-by-Step Text Solution:

1. **Understanding Telophase**: Telophase is the final stage of mitosis, which follows anaphase. During this phase, the separated sister chromatids reach the opposite poles of the cell.

2. **Decondensation of Chromosomes**: In telophase, the chromosomes that were previously tightly coiled and condensed during prophase and metaphase begin to decondense. This means they unwind and become less visible under a microscope.

3. **Loss of Individuality**: As the chromosomes decondense, they lose their distinct identities. This means that the individual chromosomes are no longer visible as separate entities; instead, they start to appear as a mass of chromatin.

4. **Formation of Nuclear Envelope**: Along with the decondensation of chromosomes, the nuclear envelope re-forms around each set of chromosomes at the poles, leading to the formation of two distinct nuclei in the cell.

5. **Karyokinesis and Cytokinesis**: Telophase is accompanied by karyokinesis, which is the division of the nucleus. After karyokinesis is complete, cytokinesis occurs, which is the division of the cytoplasm, resulting in two separate daughter cells.
