Meiosis involves two rounds of cell division that result in four haploid cells from one original diploid cell. In meiosis I, homologous chromosomes pair up and crossover occurs, then the nuclear envelope dissolves and the spindle fibers attach to pull the homologs apart. This reduces the chromosome number by half. Meiosis II then follows, where the sister chromatids separate to produce four unique haploid daughter cells each with half the number of chromosomes as the original cell.

1. Meiosis 1 and 2

2. InterphaseDiploid cell

3. Prophase IChromosomes condensing

4. Prophase ISpindle fibres start to form

5. Prophase ISpindle fibres start to form, chromosomes fully condensed

6. Prophase IThe chromosomes are crossing over, and exchanging DNA

7. Prophase IThe nuclear envelope dissolves,

8. Prophase IThe chromosomes are ready, with a bit of each other’s dna

9. Prophase IThe chromosomes are ready, with a bit of each other’s dna

10. Metaphase IThe chromosomes are ready, with a bit of each other’s DNA. The spindle fibres are ready to attach

11. Metaphase I

12. Metaphase IThe spindle fibres have attached to the chromosomes and the centromeres are about to cleave.

13. Anaphase Ithe chromosomes have split and are pulling to each end

14. Anaphase 1, the chromosomes have moved to each end, Cytokinesis is beggining

15. Anaphase I is almost over and Cytokinesis is almost done

16. Telophase I, the nuclear envelope reforms, and the chromosomes start dissolving.

17. Telophase I, the nuclear envelope is complete, the chromosomes will dissolve soon

18. Telophase I, the nuclear envelope is complete, the chromosomes will dissolve soon

19. Telophase I, the nuclear envelope is complete, the chromosomes will dissolve soon. The Chromosomes will build their sister chromatids, and the cell will prepare to split

20. Interkenesis, the cells rest, and produces proteins.

21. Interkenesis

22. Interkenesis

23. Interkenesis

24. Prophase IIthe nuclear membrane dissolves again, but there is no sharing of dna this time

25. Prophase IIthe nuclear membrane dissolves again, but there is no sharing of dna this time

26. Metaphase II, the chromosomes have aligned themselves.

27. Metaphase II, the chromosomes are aligned

28. Metaphase II, but the lower cell is going through Anaphase II, the chromosomes are moving to each end of the cell

29. Anaphase II, the chromosomes are moving to each end of the cell

30. Anaphase II, the chromosomes are moving to each end of the cell

31. Anaphase II, with cytokinesis beginning

32. Telophase II, the cell’s nuclear membrane is reforming, and the chromosomes are dissolving

33. Cytokinesis and Telophase II complete, 4 haploid cells are now ready.
