The stages of meiosis as shown in the diagram aree:

1. Anaphase I

2. Anaphase II

3. Prophase I

4. Metaphase I

5. Metaphase II

6. Telophase I

7. Prophase II

8. cytokinesis

Prophase I, the Chromosomes condense and become visible. and the homologous chromosomes pair up (synapsis) and exchange genetic material through crossing over.

Metaphase I shows where the Paired homologous chromosomes (bivalents) line up in the middle of the cell (metaphase plate).

Anaphase I shows the spindle fibers pull the homologous chromosomes apart, sending one to each pole of the cell.

Telophase I shows the nuclear envelope reforms around the separated chromosomes at each pole and the Cytokinesis occurs, resulting in two daughter cells, each with half the number of chromosomes (haploid) as the parent cell.

In Prophase II, the nuclear envelope breaks down again. Spindle fibers form and attach to the centromeres of each chromosome.

Metaphase II, the chromosomes line up in the middle of each daughter cell on the metaphase plate.

Anaphase II, the sister chromatids of each chromosome are pulled apart and move to opposite poles.

Telophase II, the nuclear envelopes reform around the separated chromosomes at each pole.

Answer:

1. Anaphase I

2. Anaphase II

3. Prophase I

4. Metaphase I

5. Metaphase II

6. Telophase I

7. Prophase II

8. cytokinesis

Step-by-step explanation:

The first image or diagram shows that the chromosomes are pulled apart while sister chromatitds are attached to one another. This is took place in the anaphase I phase.

In second diagram the sister chrmoatids are become unattached and moves or pulled towards the opposite poles. It is Anaphase II stage.

In the third image or illustration there is formation of synapsis complex and chiasmata which takes place in prophase I.

In the fourth image the pair of chromosome lined up on the equator this characterstic feature of metaphase I.

In the fifth image sister chromatids are line up on the equator which is take place in metaphase II.

In the sixth image chromosomes reach on opposite ends and formation of nuclear envelope takes place which is take place in telophase I.

The seventh image is showing the condensation of chromosome and adestruction of nuclear envelope as occurs in the prophase II.

Formation of cells and divide into four individual cells is the process of cytokinesis.
