KEY TERMS TO KNOW:

Very similar to Mitosis, Meiosis II’s sister chromatids are seprarted. At the end of Meiosis II, four daughter cells are created. Each cell is a haploid and cannot divide again until fertilization.

Meiosis II

Meiosis II can be divided into stages that are just like meiosis I: prophase II, metaphase II, anaphase II, telophase II, and cytokinesis II. These stages are identical in each of the haploid cells produced during Meiosis I.

MEIOSIS II

Prophase II
In the chromosome, the haploid cell come together, the spinde clings onto the kinetochore of each chromosome, the nuclear envelope falls away, and going toward the poles of the cell are the centrosomes.

Metaphase II
The chromosomes line up along the center of the metaphase plate, waiting for anaphase II.

Anaphase II

The sister chromatids separate and are move toward opposite poles of the cell by the spindle. The cell begins to lengthen towards the poles.

Telephase II

The cell continues to lengthen and the mitotic spindle deteriorates. A new nuclear envelope forms at each end of the cell and the chromosomes within may unfold into chromatin.

Cytokinese II
Splitting up between the two haploids are the cytoplasm and organelles. At the completion of Cytokinese II, four genetically unlike cells are made.
