Mitosis & Meiosis

Mitosis - Prophase

Chromosomes shorten, thicken, and become visible.

Mitosis - Metaphase

Chromosomes are arranged in an equitorial plane.

Mitosis - Anaphase

Centromere splits into 2, each sister chromatid moves towards the opposite poles of the cell (polarisation).

Mitosis - Telophase

Cytoplasm divides, nuclear membrane and nucleolus form again.

2 daughter cells with the same amount of chromosomes & genetic information as parent cell are formed (diploid).

Meiosis I - Prophase I

Chromosomes shorten, thicken and become visible.

Homologous chromosomes pair together and crossing over occurs.

Meiosis I - Metaphase I

Chromosomes are arranged in an equitorial plane.

Meiosis I - Anaphase I

Homologous chromosomes separate and move to the opposite poles of the cell.

Meiosis I - Telophase I

Cytoplasm divides, Meiosis I ends.

Meiosis II - Prophase II

Spindle fibres form.

Meiosis II - Metaphase II

Chromosomes are arranged in an equitorial plane.

Meiosis II - Anaphase II

Centromere splits into 2.

Sister chromatids separate and move to the opposite poles of the cell (polarisation).

Meiosis II - Telophase II

4 gametes are formed with half the number of chromosomes as the parent cell (haploids).
