Definitions:

Telophase

The last stage of mitosis and of meiosis I and II when, having reached the poles, chromosomes become decondensed, and a nuclear envelope forms around each group.

Mitosis

The division of the cell nucleus resulting in two daughter nuclei, each with the same number of chromosomes as the parent nucleus; mitosis consists of prophase, prometaphase, metaphase, anaphase, and telophase. Cytokinesis usually overlaps the telophase stage.

Homologous Chromosomes

Pairs of chromosomes in a diploid organism that have the same gene sequence, inherited from each parent, and pair up during meiosis.

Staining Patterns

Distinctive appearances that cells or cellular components exhibit after being stained with specific dyes, helping in identification.
