Meiosis is the process of cell division that produces gametes with half the normal number of chromosomes. It involves two rounds of division: meiosis I and meiosis II. In meiosis I, homologous chromosomes pair up and separate, reducing the chromosome number from diploid to haploid. Meiosis II then separates the sister chromatids, resulting in four haploid daughter cells each with a single set of chromosomes.

1. Meiosis:
 The form of cell division by which gametes, with half number of
chromosomes are produced.
 Meiosis is sexual division.
 Diploid 2n to haploid 1n.
 Involve two divisions: meiosis I
 meiosis II
 Sex cells divides to form gametes.

4. Prophase I:
 Longest and most complex phase (90 %).
 Chromosomes condenses .
 Synapsis occur: homologous chromosomes
comes together to form a tetrad.
 Tetrad: is two chromosomes or four
chromatids.

5. Homologous chromosomes:

6. Prophase I:

8. Metaphase I:
 Shortest phase.
 Tetrad align on metaphase plate.

9. Anaphase I:
 Homologous chromosomes
seperate and moves towards
opposite poles.
 Sister chromatids remain attached
at their centromeres.

10. Telophase I:
 Each pole has haploid set of
chromosomes.
 Cytokinesis occur and two haploid
daughter cells are formed.

11. MEIOSIS ll:
 No interphase.
 No more DNA replication.

12. Prophase II and Metaphase II:

13. Anaphase II:

14. Telophase II:
 Same as telophase in mitosis
 Nuclie forms.
 Cytokinesis occur.
